Mark Zuckerberg delights in tweaking his lumbering rival Google. He stole the company's operations chief, and some of its best engineers. Now he's mocked the company's "little" rival social network, successfully provoking a response. Such a twerp!

Zuckerberg dropped a little provocation at a Charlie Rose taping the other day: "Google, I think, in some ways, is more competitive, and certainly is trying to build their own little version of Facebook." Ha ha, did someone just call you small, Google? You wouldn't let that get under your skin now, would you, what with new CEO Larry Page trying to make the company act more like a startup? "We're delighted to be underestimated," Google VP Bradley Horowitz told Bloomberg. Ya, they're quietly seething. Troll: successful.
