Meet the Facebook Mafia
You probably already know about the PayPal Mafia—the influential and wealthy group of former PayPal executives that spawned many of Web 2.0's biggest hits. But soon, there may be a new generation of Silicon Valley start-up bosses in town.
When Facebook goes public, these current and former Facebookers-turned-entrepreneurs and venture capitalists will be worth billions. What's more, this group is rich in ideas and connections. So when they're not backing promising start-ups, you can bet they'll be tinkering on something of their own. Here are the Mafiosos to watch.
