If Facebook were a nation, it would be outranked by only China and India in population:
Facebook, the social network created in the dormitories of Harvard six years ago, said on Wednesday that it now had 500 million members.
The company has grown at a meteoric pace, doubling in size from a year ago and pushing international competitors aside.
Each month, Facebook says, more than 30 billion photographs, links to Web sites and news articles are shared through the site, and its members spend roughly 700 billion minutes there.
“This is an important milestone for all of you who have helped spread Facebook around the world,” Mark Zuckerberg, the company’s 26-year-old chief executive, said in a company blog post.
A half billion people, and they’re all playing Farmville.
