Twitter’s march towards world domination continues apace. This morning comScore released its global numbers for March, 2009. Worldwide visitors to Twitter.com increased 95 percent in the month of March from 9.8 million to 19.1 million, according to its estimates. This compares to 9.3 million visitors in the U.S. alone.

These numbers only count visitors to Twitter’s Website, which is not the same as active users and also does not include people who interact with Twitter via desktop or mobile clients (a large portion of users). But the comScore numbers provide a good proxy for Twitter’s overall growth, which was helped recently by Ashton Kutcher’s race with CNN to one million followers, and Oprah’s subsequent adoption of the service.

If Twitter can keep this rate of growth up, it should cross 50 million visitors by summer.

Most web application developers have been there: your monitoring system shows nothing but green lights, yet the app is down or not functioning the way it should. Traditional web monitoring services often don’t dig deep enough to detect glitches in the application code, and database or find that problems arise with bugs in Ajax, Flash or Silverlight front-end applets.

German startup iOpus is today unveiling the public beta of a product it claims offers a solution for many a developer or website owner who would like their monitoring services taken up a notch. Enter AlertFox. (free Pro accounts for 100 users, see below)

What AlertFox does is provide in-depth monitoring of rich internet applications (RIAs), offering a potential solution for many SaaS and Web 2.0 web service providers out there who are not satisfied with a simple uptime checker that only provides superficial information without detecting the root cause of problems. AlertFox runs directly from the browser (with support for both Firefox and Internet Explorer) and is capable of keeping tabs on the functioning and performance of sites built with ActiveX, AJAX, Flash, Flex, complex HTML or Silverlight technology.

Another aspect that sets AlertFox apart from most traditional monitoring services is the real-time monitoring of transactions, e.g. the entire checkout process for an e-commerce store instead of only its uptime. This should come in handy for online businesses for which a smooth buying and selling process makes all the difference in the world.

The company is following the freemium approach for its business model, which is subscription-based and as far as I can tell extremely moderately priced. Users can get started with a free account, which covers worldwide monitoring and other basic features but only supports one user and use within the Firefox browser. You’d need to sign up for a Pro account (starts at $49 per month for the time being as a promotional offer) for transaction monitoring with both Firefox and Internet Explorer, support for up to five users and 100% monitoring of Flash, Ajax and Silverlight applications.

We’d love for you to take it for a spin and tell us if it lives up to its promise, so we’ve arranged for the company to give away 100 free Pro2 accounts, valid for two years. All you need to do is quickly sign up for a free account and send an e-mail to techcrunch-at-alertfox-dot-com. The first 100 readers to do that will be upgraded without charge, and are expected to come back and share their experiences in the comments.

If it seems like Twitter is growing faster and faster each day, that is because it is. ComScore has released its March numbers for the U.S., and it estimates that unique visitors to Twitter.com grew 131 percent between February and March to 9.3 million visitors. No wonder Twitter is more popular than Britney.

Not only did Twitter more than double the number of people that go to its site in a single month, but it accelerated its growth from the 55 percent rate it experienced in February. These numbers do not include international visitors, nor do they include all the usage on desktop and mobile clients, which is significant in Twitter’s case. But it is a useful proxy.

So to just to give a sense of the type of growth Twitter is going through, here is the month-to-month growth in U.S. unique visitors so far this year:

March, 2009: 131%
February, 2009: 55%
January, 2009: 33%

In February, comScore estimated that Twitter.com had worldwide 9.8 million visitors worldwide and 4 million U.S. visitors. If that 41 percent ratio of U.S. visitors to total worldwide visitors still holds (in January it was about the same), it would mean that Twitter.com attracted more than 20 million unique visitors worldwide. ComScore releases international figures later in the month.
