This is a guest post by Robert J. Moore, the CEO and co-founder of RJMetrics, an on-demand database analytics and business intelligence startup. His last guest post was an analysis of Twitter user data.

It’s no surprise that Chatroulette is the latest media darling. It has all the elements of a good story: technology, mystery, celebrity, and sex. If you haven’t heard of Chatroulette, this Daily Show segment is a good primer.

We were itching to study Chatroulette in a RJMetrics Dashboard, but no one seemed to have any good data for us to explore. So, we decided compile the data ourselves by leveraging Chatroulette Map, some scrappy programming, and a passionate tech community. We soon had detailed data on 2,883 Chatroulette sessions that tied users to geography, gender, appearance, and more.

Here are a few highlights from our findings:

• About half of all Chatroulette spins connects you with someone from the USA. The next most likely country is France at 15%.
• Of the spins showing a single person, 89% were male and 11% were female.
• You are more likely to encounter a webcam featuring no person at all than one featuring a solo female.
• 8% of spins showed multiple people behind the camera. 1 in 3 females appear as part of such a group. That number is 1 in 12 for males.
• 1 in 8 spins yield something R-rated (or worse)
• You are twice as likely to encounter a sign requesting female nudity than you are to encounter actual female nudity

How We Did It

Thanks to RJMetrics, the analysis was easy. Getting the data, however, was a bit of a challenge. The good news, however, is that a roulette wheel is the statistician’s best friend. The central limit theorem tells us that a large set of random observations allows us to draw high-confidence conclusions about the underlying data set.

We started our process at Chatroulette Map, an awesome new site that plots screenshots from random Chatroulette sessions on a map.

It’s a little-known fact that anyone you chat with on Chatroulette can determine your IP address using a program like Wireshark. Chatroulette Map uses this IP data to geolocate and map random chatters on their website (along with still photos from their chats).

Chatroulette Map is also nice enough to expose all of its data points to anyone who clicks “View Source.” Right in the raw source code of their homepage is the image URL, latitude, longitude, city, state, and country of every chatter on their map. As an added bonus, the file name of each image is a UNIX timestamp of when it was taken. Jackpot. (Note: we tried contacting the creators of Chatroulette Map to participate in this story but did not receive a response.)

Once we had photos, times, and locations, we needed data on what was happening in each chat photo. We coded up a quick webpage that displayed a random photo from the data set and asked some basic multiple-choice questions about that photo. These included questions on age, gender, and what the person in the photo was doing. We coded up the backed so that a photo wouldn’t be taken out of rotation until two votes from different IP addresses provided an identical set of answers.

We posted the link to Hacker News on Saturday night. In under two hours, we received 10,770 photo assessments from 1,012 distinct IP addresses. Every photo received a corroborated profile. We had our data.

Five minutes later, the data was loaded into a hosted dashboard on RJMetrics and returning the results you see below.

Caveats

Before we get to the data, we should point out the uncontrolled inputs that could be skewing these results:

• We know nothing about how Chatroulette matches up chatters, and we act on the assumption that pairings are truly random.
• We know nothing about the methodology used by Chatroulette Map. If they excluded data points for any reason or did not sample randomly, our analysis could be skewed.
• Geolocation by IP address is an imperfect science that is typically only accurate within a few dozen miles. It can also be thrown off by users taking advantage of proxy servers or using other techniques to disguise their IP addresses.
• Human image recognition is imperfect (even if mitigated by our vote convergence system). Any images that were judged incorrectly could skew the results.
• It’s also important to note that statistics about “the average chat session” (which we present here) are not the same as stats about “the average user.” For example, imagine if female chats averaged 100 seconds each, but male chats averaged 10 seconds each. Even if there were equal numbers of male and female users, males would enter the pool more often and would therefore appear in front of you more often, making the “average session” more likely to contain a male chat partner. Because of this, all of our statistics are about the average session and not the average user.

The Results

Gender

As you might expect, you’re most likely to encounter a solo male in any given chat session. 72% of our chat sessions were with solo males. Interestingly, 11% showed no person at all while only 9% showed a solo female. So, if you’re looking for women on Chatroulette, be forewarned: you’re more likely to encounter an empty chair.

Also interesting is the prevalence of groups on Chatroulette. In all, 8% of chats featured a group of people (4% all-male, 2% all-female, and 2% mixed). If you include groups, your chance of encountering a female grows to 13%. However, this means that if you do encounter a female, there is about a 1 in 3 chance that she will be part of a group. In contrast, the chance a male will be part of a group is only about 1 in 12.

Age

This analysis excludes cams where age could not be estimated. As you might expect, most people were young adults (about 70%). About 20% were under 20 and about 10% were 40 and older.

When we combine age with the gender statistics that we tracked above, we learn even more. For example, females tended to be younger than males, with 23% under 20 (vs. 18% for males). Only 3% of females were over 40 (vs. 8% for males).

Groups of females were even younger. Female-only groups were “Teen or Younger” 65% of the time, while groups of males were “Teens or Younger” only 36% of the time. There were no groups whatsoever of people 40 or older.

Location

47% of the Chatroulette participants measured were from the United States. The most popular countries are shown below:

When we combine geography with gender and age, we learn even more:

• Italy had the highest concentration of solo males at 98%. It also had the highest concentration “Men over 40″ at 13% (more than 3x the US rate of 4%).
• The US has the highest concentration of groups at 13%, followed by The Netherlands at 9%.
• Canada had the highest concentration of solo females at 13%, followed by the US at 10%.

Perverts

If you’ve ever used Chatroulette, you probably noticed that not everyone is there just to chat. Some users, which we have affectionately labeled “perverts,” fit into any of these three categories:

• Appear to not be wearing any clothes whatsoever
• Are displaying explicit nudity
• Appear to be committing a lewd act

The overall pervert rate in Chatroulette is 13%. This means about 1 in 8 chat sessions will have something decidedly Rated R (or NC-17) on the other end. Of the perverts that were identified, only 8% were female. Combined with the overall female rate, that means less than 1% of chats feature a female pervert.

Below, we see the “pervert rate” by country:

The United Kingdom dominates the rankings here with a pervert concentration of 22%! Turkey, France, and Germany tie for second place with rates of 15%. Bringing down the global average is the United States, which boasts the lowest pervert concentration of the bunch: 10%.

Also worth mentioning are the users who display signs (like the one below) requesting female nudity.

Signs like this make up between 1% and 2% of all chats. This means that you’re twice as likely to encounter a sign requesting female nudity than you are to encounter actual female nudity.

Validation

In trolling through the thousands of photos collected by Chatroulette Map, I came across this extremely interesting image. It contains a statistical breakdown of what this user saw during his many Chatroulette chat sessions. Sound familiar?

These stats appear to be based on a data set of 1,090 points (pretty impressive for a single user). The numbers are generally in the same ballpark as ours (although we observed a higher pervert rate). We’re not sure who was behind this, but we like their style– they managed to sum up the gist of this blog post in a single image.

Conclusion

Scarcity of the data made this project both challenging and exciting. In an ideal world, it would be great to analyze things like average session length based on different attributes, chat user return rates, cohort analysis, and more. Because of the mostly-anonymous nature of Chatroulette, that data will be hard to come by. For now, at least you have a better idea of what you will see when you hit that Next button.

I mentioned in my last post that mobile is bridging the digital—not to mention analog— divide in India, with almost half as many new mobile accounts being opened just last January as there are Internet users in the entire country.  And there are a host of interesting companies seeking to leverage that network as some kind of rudimentary, literally “dial-up,” Internet that extends far beyond the country’s 50 million or so Web users.

One of the most ambitious companies I met with during my last trip to India in November was Eko, a mobile banking company. There are a few SMS-based bank applications in India, but Eko differs because the phone isn’t just another channel for the account—it is the account. You make payments and transfer money simply by dialing numbers. It’s so simple, you don’t even need to understand SMS to use it.

It’s an ingenious offering that doesn’t try to be everything to everyone. It aims squarely at the unbanked—some 60% of India’s huge population. For now, Eko is focusing on the 1,000 kilometer corridor between Delhi and Bihar.

It’s a textbook case of the how hard it is to build something incredibly simple within a sandbox of tight constraints—yet that simplicity is the same thing many would argue caused Twitter’s 140-character missives to become so universal. There are no extra bells and whistles with Eko’s service because there’s no room for them, and at the end of the day, probably little need for them.

The accounts are actually held by the State Bank of India, which insures up to 100,000 rupees per account, but Eko’s customers don’t ever go into banks. The “tellers” are the tiny corner groceries that dot every neighborhood and street corner in India’s crammed urban areas and expansive rural areas. They are the center of commerce for those living on intermittent jobs, tips and handouts. These stores sell medications by the pill, shampoo in tiny sachets, cell phone minutes by the Paisa, and frequently extend credit when needed. Eko just seeks to give this already trusted, daily-visited vendor one more thing to sell.

The interface is simple enough for anyone to use, regardless of language or literacy. Just like filling out a check requires you to enter the payee, how much you are paying and sign it and Eko transaction has the same three elements. Eko customers type the bank’s short code, then an asterisk, then the mobile number of the person you are paying, then an asterisk, then the amount, then another asterisk. Then comes the signature. That’s the tricky part, but also the most important, because the account is solely on phones, which can be stolen.

Eko’s founder Abhishek Sinha (pictured above amid his signage) wanted to come up with a cost-affective equivalent of an RSA token, so he created a paper version of it. Account holders get little booklets with pages of 11-digit codes. Seven digits of it are random numbers, with four randomly placed black marks, where the person enters his or her PIN. So even if the booklet is stolen, no one knows the PIN number and they still can’t access the account. There’s a VeriSign logo on the back of each booklet. Sinha reached out to VeriSign to see if they could come up with a better solution– instead they endorsed his.

Freedom from always having to carry cash has obvious safety and empowerment implications. But this is a hard company to build out broadly in a country like India. The very strength of the model to truly reach the unbanked—turning those trusted, neighborhood grocers into tellers—inherently makes it costly and time-consuming to build because there are so many of them serving relatively small neighborhoods and villages. Eko has 30,000 account-holders right now. “I thought it’d be a million by now,” Sinha says. “We’ve had a lot of false starts.”

There’s a cost-time trade off. Since the service launched in late 2007, Eko was outsourcing the management of the grocers to a third party who sells multiple things through the channel already. But evangelizing the product takes more hand-holding, so the number of accounts wasn’t growing. Since November, Eko has taken over the management of these grocer accounts assigning employees to each neighborhood and investing in street promotions, blaring its Bollywood-eque jingle extolling the virtues of banking and bedecking stores with in-store signage. Now new accounts are soaring. Eko had just 6,000 accounts before the switch in strategy. It added 10,000 in January and is now adding 10,000 every 15 days.

But costs are going up too. Sinha, who made some money founding a previous company Six DEE Telecom Solutions, has self-funded the venture until now, and in Eko got a $1.78 million grant from the World Bank and The Gates Foundation. But that money will run out this year. He’s working on raising a venture round now—and hoping to get a whopping $10 million. In his previous startup he says he was turned down by literally hundreds of VCs and says that this time it’s going a lot better. Indeed, he jokes, it’d be hard for it to go worse. For one thing, he’s learned a 60 page PowerPoint is overkill.

Like VNL, the solar-powered, mobile equipment company that was 100% bootstrapped by the founder, this is one of those companies that is tricky to build in India. There’s a huge social need and business opportunity if it hits scale, but there’s also a lack of capital to support deals like this. A venture firm is more comfortable in the $3 million-to-$5 million range and a private equity firm would demand a lot more maturity of the business before it would invest. Had Sinha not invested his savings in the project, it likely wouldn’t have gotten this far.

I asked several times if Sinha was worried. What if he couldn’t raise the money? He laughed every time I asked with a look in his eyes of “Do you know how hard it actually is to be an Indian tech entrepreneur?” He says he’s been through enough to know there’s always a way. (Regular readers know there’s a word for that.)

Last time I was in India I wrote about the amazing business model innovation that had allowed telecom operators in India to make money on a paltry $6 a month per average user. That compares to a desired average monthly payment of $50 or more in the U.S.

The results have been phenomenal—550 million people in India have phones, and it has transformed the poorer service economy by giving them an affordable way to be reached and arrange jobs. Just last month, nearly 20 million new mobile accounts were opened. That’s more than double the people than have high speed Internet in the entire country. Even in slums where people live on less than $2 a day, everyone has a phone. If “Slumdog Millionaire” was more accurate, Jamal wouldn’t have had to go on TV to find Latika. He could have just called her, or worst case, called a few friends until he found her number.

It’s unequivocally India’s most successful infrastructure achievement —despite some mounting concerns about the effects of all those towers dotting nearly any urban rooftop that can hold one. And a host of exciting applications are being built on top of this invisible thread that connects a disparate country with a vast terrain and even bigger gulfs in language, literacy, income, religion, language and living standards

But amazingly, when Rajiv Mehrotra (pictured below) looked at the existing telecom penetration in India, he saw failure. What about the people who can’t afford $6 a month or live too far to get service? Don’t they deserve to be connected as well? The result was VNL, a company that’s already gotten a good deal of press and acclaim for its dead-cheap, low-maintenance, Ikea-like easy-to-assemble, solar-powered base stations that extend existing mobile footprints into rural villages for a fraction of the price, allowing the remotest, poorest villages to have mobile phones in every household at drop-dead low prices. “We are the bottom of the bottom,” boasts Mehrotra, practically daring competitors to try to play his low-cost, super-durability game.

The World Economic Forum named it one of 26 Technology Pioneers, and just last month VNL won the Mobile World Congress’s Green Mobile Award. Time called it a “Tech Pioneer that Will Change your Life” and Fast Company named it one of the world’s 50 Most Innovative Companies in the world.

I met with Mehrotra at the company’s headquarters in Gurgoan during my November trip to India. This time I wanted to see its technology live in villages and hear first hand what the impact had been. I traveled to a village that had now had phones for about seven months to see how the technology had changed their lives. Of the 500 families spread across this area, almost all of them had a phone—and most for the first time.

The majority of the people I spoke with said the first calls they made were to family members, and that the biggest impact was the ability to stay in touch with family, to know when there was an emergency and be able to respond quickly.

But there have been business effects too. One man (pictured here) has a business operating several trucks traveling between this village and Delhi and before he’d have to ride on a bike between them to coordinate them. Now he can sit at home and just call the drivers. He installed one of VNL’s small base stations on his roof, and he said it had increased his standing among his peers—he is frequently the one called on to settle disputes now. And now they can just call him. Similarly wives will call husbands out in the fields when its time to come in and eat, rather than trudging out to get them, allowing them to focus on kids and the housework.

Another woman (pictured to the below) I spoke with was a widow with six kids and 21 grandchildren. (So many, she actually had to ask someone else how many she had.) As grandkids clambered in and out of her lap, she explained that she gets pension checks from the government, but the delivery used to be spotty. Before her phone she had no recourse but to travel to Delhi to inquire about it. Not exactly something she relishes, having lived her whole life in this village and only been to the big city twice. Now she can call the office and gives them an earful. Not surprisingly, the checks have started to come more regularly.

Another man (pictured to the right) told me he felt more connected to the rest of India as a result of having a phone. This village is surrounded by mountains, and he said that he felt “imprisoned” and cut off, despite being just a few hours drive from Delhi. Now he has a renewed interest in politics and what’s happening in other villages and the country at large. This man had only had his phone for six months, but he expected it would change his life in ways he couldn’t articulate or imagine. “Since the day I got this, my life has already changed,” he said through an interpreter.

Indeed, Mehrotra says it’s already having a ripple affect on the politics of Rajisthan—the state between Pakistan and India where VNL did its first installations. Politicians come through and make promises and villagers demand their cell phone numbers and call to check up on whether those promises are kept. “They have to be accountable,” Mehrotra says. “They can’t wriggle out.”

These phones are not just a nice-to-have, they’ve quickly become a must have for these villages, deeply tied to the way they make money, participate in their government and retain closely important family relationships. And these ripple effects are only now beginning. Think of what the impact will be when there are better programs for marketing crops, saving money and even learning and game playing rolled out on these very basic phones. Life will always be different in a village or a city, but India can at least gain some basic common denominators between the two.

Mehrotra is a big believer in the Ghandian mantra: Change the villages and you change India. He’s a serial entrepreneur who has already built businesses rolling out satellite TV and landlines to rural areas, but he thinks this company will have a bigger impact than anything else he’s done and is the one with the real potential to go global. It bears noting that he’s invested all of his own money in the project—and it’s taken far more than he expected.

This is not a cheap venture—Mehrotra has invested more than $100 million in the last five years and is still investing more. But I’m not sure it could be built any other way. I don’t think there’s the venture capital appetite or risk profile in India to fund something like this and most of the mobile equipment companies Mehrotra talked to back when he started thinking about this insisted it couldn’t be done. Once he built it he’d take equipment and operator executives out to see it and they still couldn’t believe it. They were making calls to test the quality from different areas of the village trying to find pockets without a signal. “They were climbing on the antenna and shaking it like monkeys trying to break it and they couldn’t,” Mehrotra says.

From a business point of view, the operators love VNL because it cheaply expands their existing footprint. The equipment operators aren’t so sure. In theory, VNL isn’t competing with them because they’re not going into the cities. Now that VNL has proved this model works, could a larger established vendor steal the market? The best chance of that would likely come from a Chinese powerhouse like Huawei. That said, any vendor that builds such a low cost solution that’s too good will risk eroding his higher priced systems designed for urban areas. “They’ll say ‘Give it to me in the city too.’ ” Mehrotra says.

All these awards aside, this is the year for VNL to prove it’s really a viable business. And Mehrotra says there are some surprises in store. In terms of market, VNL is already rolling the technology out in other countries and in terms of product they’re not done with just simple mobile access. The countries are likely in Africa and perhaps Latin America, and my guess is the new functionality will entail turning on some kind of Internet access through the existing base stations. Expect much more on this newly minted international do-gooding darling in 2010.

As I’ve made abundantly clear over the past several days, just about every service that has anything to do with location is launching something at the SXSW festival which starts tomorrow in Austin, Texas. Don’t believe me, here’s a small sampling (Foursquare, Gowalla, Loopt, Whrrl, Plancast, Brizzly, Twitter). So, how are you going to wrap your head around all this location data? SimpleGeo has an awesome way.

Vicarious.ly is a real-time location-based stream of information presented in a nice visual way. While the plan is to eventually launch one for many different cities around the U.S. and eventually the world, the first one is based around Austin, for SXSW. To make it, SimpleGeo partnered with BlockChalk, Brightkite, Bump Technologies, Flickr, Fwix, Foursquare, Gowalla, and Twitter to pull all of their location data and place it both in a constantly-updating stream, and put data points on a Google Map at the top of the page. These data points are represented by the logos of the various companies, so it’s easy to follow visually.

Those concerned about the privacy implications of this need not worry, Vicarious.ly doesn’t pull actual user names from the companies mentioned above. Instead, they simply note that “someone” checked-in at a venue. They do, however, give the venue name, which is a hyperlink. So if someone just checked into Stubb’s Bar-B-Q in Austin on Gowalla, you’ll see a link back to the Gowalla page for that venue. Likewise, if someone uploads a geotagged picture to Flickr, you’ll see a thumbnail of the picture in Vicarious.ly’s stream, and clicking on it will take you to that picture’s Flickr page.

It’s fairly amazing to see just how much activity there is even today, the day before the conference starts. Tomorrow and the weekend should be insane. “The amount of real-time, location-based information we’re indexing is staggering.  We wanted a powerful way to showcase that, so we built Vicarious.ly and targeted the launch to coincide with a massive gathering of geeks,” co-founder Matt Galligan says about the project.

You’ll note just how much of the activity are check-ins from either Foursquare or Gowalla. Those two are likely to be the two main competitors in the location war that will take place this weekend. (If you’re surprised not to see tweets in the stream, it’s a bug that SimpleGeo hopes to squash tonight).

Last November, MSNBC acquired the Twitter account @breakingnews, which was started as a basic newswire by Michael van Poppel and gradually grew to 1.4 million followers (it’s now up to over 1.6 million). A month later, MSNBC announced that it had acquired BreakingNews.com, which has become a web portal for the online newswire. And today, it’s managed to complete the trifecta: MSNBC has just launched a Facebook Page at Facebook.com/BreakingNews.

MSNBC spokesperson Gina Stikes says that the new Facebook account will only send updates for the biggest stories to break (you can still use its other feeds if you want to receive every story to come from the service). The page is obviously still quite new (it only has 645 fans right now), but you can expect that the grow quickly.

Just how quickly is the big question, though: we’ll have to wait to see if MSNBC will be able to leverage its large community on Twitter to establish its Facebook page.  In any case, it’s managed to take ownership of the term “breaking news” across a large swath of the web, which is no small feat.

Let the record show: I think motion controllers, like the Wii , Sony Move , or Microsoft’s Project Natal , are sorta dumb. They simply don’t seem to be precise enough for my tastes—I’m far too used to a mouse and keyboard to give that up for the “thrill” of flailing my arms in the arm like the robot from Lost In Space. But it wasn’t always like that.
