Hard-partying web maven Sean Parker, now that he's working as a venture capitalist, for Peter Thiel at the Founders Fund, will have to be more discreet. James Hong, another legendary Valley carouser, is now teetotal, and prefers relaxing afternoons with Lance Bass on the beach. Philip Kaplan, founder of Sequoia-backed ad network Adbrite, left his wild side back in New York. So thank god for Jordan Mendelson, co-founder of the Snocap music site, who hasn't turned up to a holiday party without his coven in attendance. Jordan Mendelson, the competition's wilting: you are Valleywag's bad boy of the season. Photos, from the Yelp party, after the jump.
