Facebook hits 350 million users, closes 3,500 accounts

Social networking giant Facebook reached a new milestone this week, surpassing 350 million registered users. Founder Mark Zuckerberg noted the occasion in a blog update, where he outlined how his company achieved that number and where it is going from here.

Zuckerberg also used the time to address concerns about changes to Facebook's privacy policies. A major change will be the nature of networks, where regional networks are disbanded and users are presented with more confirmations on what information is exposed. Other privacy options will be simplified by combining many actions.

In the same breath, Facebook also shut down nearly 3,500 accounts in cooperation with law enforcement to remove Internet predators from the site. Facebook has made a public effort to keep the site clean from criminals for some time, but the sheer size of the site may make that increasingly difficult.
