It's hard to find a man more bullish on social than Bing Gordon. The Kleiner Perkins partner will be spearheading the firm's new sFund and, like John Doerr, fully believes that the era of social is just beginning.

Sounds like KPCB— and its rat pack of hot-shot web companies (Facebook, Amazon, Zynga, etc.)— will need a bigger boat. Videos with Gordon and CafeBots ahead.
