This week Facebook hit a landmark number: 500 million registered users. Put into geographical context, Facebook has enough members to be the third most populous country in the world. At the head of this virtual country sits 26-year-old Mark Zuckerberg.
Zuckerberg is the founder and CEO of Facebook, which he started while attending Harvard just six years ago. And while he may have never finished Harvard, no one can call him a quitter.
