I think one area people overlook with Facebook is that they pretty much leave social games to eat their lunch. There's only so much they can squeeze out of advertising (it's already starting to feel over-priced). In Japan Mixi got eclipsed by Gree when it came to making an IPO because Gree focused on games and selling virtual goods. Gree had way more profits and growth potential. They eventually opened up to social gaming but their profits are still strong. Ditto Mobage. The way Zynga built on Facebook is similar to how MicroSoft and Intel took off of IBM. Facebook's valuation and growth potential would be astronomical if they owned a piece of social gaming instead of just providing infrastructure.
