The world's most popular social networking site is about to mark another milestone. Rumors from across the Internet (via All Facebook) believe an announcement should be imminent. Facebook has already sent out an internal email celebrating the news, and it is believed that the new tab designs will hit shortly after the big announcement, on August 1.
Half-a-billion people is a staggering number. At this rate, in another couple of years Facebook could crack a billion. The party for that one is going to be off the chain, assuming some new social media site doesn't come along and do to Facebook what it did to MySpace.
