According to Facebook, as of June 2012, it has 3,976 full-time employees. If that seems like a lot, you’re bugging. Consider Facebook’s reach. For a company that is mentioned alongside tech behemoths like Apple, Amazon, Microsoft, and Google, that’s a slither of a workforce. If you still don’t agree, look at the latter company: In its 2012 Q2 report, Google said it employed 34,311 people worldwide. Hell, even Groupon, a company that basically serves up coupons, has more people, with 10,000 employees. Think about that the next time Facebook goes down.
