Chad Hurley of Youtube, Marissa Mayer and Sergey Brin of Google, and even MC Hammer, all make it into this short video by Kara Swisher of All Things Digital, who takes us inside Silicon Valley’s A-List holiday parties. As you might expect, they’re rather low-key affairs. Very biz-cahj. I mean you won’t see Liza lounging on Halston’s ultrasuede couch, powdering her nose with Bianca and the boys, but you will see Chad wink for the camera, witness Sergey getting tipsy, and meet a male Santa with boobies. I suspect that’s about as risque as it gets in that world.
