We were wrong about the identity of the Viking-clad Facebook founder living it up on Friday night. It wasn't Sean Parker, who, we hear, is in Spain. (Sorry about that, Sean!) VentureBeat claims it was Dustin Moskovitz, Facebook's VP of engineering and one of the three official Facebook cofounders. The person in question wore a Viking helmet and a fur skirt. Nothing else. (Ed.'s note: Rawr!) Our tipster must have been pretty hammered, because the description supplied — "tall, has dirty blond hair and glasses, and is not particularly attractive" — fails on two out of four counts. Moskovitz has brown hair and is, according to AllThingsD's Kara Swisher, "such a fox." Again, our apologies. But we're glad Moskovitz is taking notes from Parker on how to get down. Update: We now hear Moskovitz was in Palo Alto Friday and Saturday. Can anyone identify that fur-skirted man for us? (Image by VentureBeat)
