Facebook says it's hit the black & 300 million users

Facebook said in its blog today that it had hit the 300 million user mark and that it had started making money.

The company has been quickly achieving population targets that it likes to compare to countries. Right now, if the online community was a country, it would be the world's fourth-largest: after China, India and the U.S. (Although if you considered the European Union a country, that would make it fifth, according to the CIA World FactBook.)

Founder Mark Zuckerberg also said today that the company had started making money, although they used the rather techincal term "free cash flow positive":

"Earlier this year, we said we expected to be cash flow positive sometime in 2010, and I'm pleased to share that we achieved this milestone last quarter,'' Zuckerberg said in a statement. "This is important to us because it sets Facebook up to be a strong independent service for the long term."

Some other fun FB stats: about 70 percent of its users are outside the United States - and the fastest growing demographic is people over age 35.
