In an interview on MSNBC's Today Show, Facebook founder Mark Zuckerberg told Matt Lauer that the social networking site is growing in the US at the pace of nearly one million users a week. In fact, a quick peak at AllFacebook's demographic statistics suggests that Facebook is actually growing faster than declared.

And, even more remarkable were Facebook's worldwide growth figures stated by Lauer - the over 5 million weekly users indicated the numbers to be even higher than those mentioned by the company's lately-published data!

With regard to the money Facebook makes from the huge number of users, Zuckerberg said that there were a "few different lines" of revenue, were supposedly growing "very quickly". He also expressed satisfaction at the way the company's attempts were yielding results in the face of the economic downturn.

Talking about Facebook's demarcation from its bigger US rival social network MySpace, and microblogging site Twitter, Zuckerberg pointed out Facebook features like easy photo-sharing and privacy controls.

The interview, which also touched the recent brouhaha about the alleged changes made to Facebook's terms of service, had Zuckerberg admitting that when he founded the site in 2004, he was simply looking at services that would enable users share information on the web; not once prophesying that Facebook would become one of the mediums for exchange of such information!
