A little more than a month after announcing it had, Facebook has reached 175 million active users--the statistic the social-networking site prefers to use, rather than registered accounts overall.
Dave Morin, who runs Facebook's application platform team, announced the milestone Friday evening on his Twitter/FriendFeed. Facebook reached 150 million after reaching 120 million and after reaching 100 million.
While Facebook got its start at Harvard University in Cambridge, Mass., in 2004, most of this recent growth is coming from outside the U.S.
"This includes people in every continent--even Antarctica," CEO Mark Zuckerberg wrote in a blog post last month. "If Facebook were a country, it would be the eighth most populated in the world, just ahead of Japan, Russia, and Nigeria."
However, as we have pointed out before, server power is expensive, especially overseas. Facebook has raised a ton of venture capital, is, and says it's in good financial shape. That brings backs the question, however, if it's growing faster than it ever expected to.
