He told Valleywag that he was worried about the Hawaiian heat of David Hornik's The Lobby conference, and decided to go short. By himself. Using the No. 5 setting on his electric razor. And we're willing to wager that the barber's blood-alcohol content was a bit north of .08, cause, really, who cuts their own hair while sober?

Now that the haircut question is settled, let's ponder a more tantalizing query: Why was Rose seen arriving and leaving the party with Lara Doucette, better known as Lala on the Web video show TikiBarTV? We had high hopes for his reunion with ex-girlfriend Sarah Lane once we saw them together in Hawaii a few weeks ago. Perhaps this is a rekindling of another old flame? Kevin and Lala looked awfully cozy at last year's Revision3 launch. (Photo by b_d_solis)

Peron's place, which Culver is renting, is amazing. The backyard is built like a treehouse, with hidden stairways leading to the an outbuilding that doubles as a blacklight garden and hot tub. A model of the Golden Gate bridge serves as a walkway connecting the second floor to the guesthouse. Oh, and there are full-grown pot plants everywhere you turn.

The party had the feel of a high-school kegger, as if Web 2.0 High prom king Kevin Rose had convinced his venture capitalists to go away for the weekend and leave the liquor cabinet stocked. Pownce cofounder Leah Culver danced around the kitchen lip-synching to "Lip Gloss." On a screen, Randi Jayne, Facebook CEO Mark Zuckerberg's sister, debuted her latest viral video, a very clever iPhone parody. By 11 p.m., the kegs were kicked, and people stood around holding red plastic cups, hoping in vain for more liquor. Attendees included just about every boldfaced name from the San Francisco Web scene: StumbleUpon's Garrett Camp; Om Malik and Liz Gannes from GigaOm; Sarah Lane, Martin Sargent, and David Prager from Revision3; and recent New York Times profile subject David Ulevitch from OpenDNS.

And of course, there was some drama. A group of wannabe gangbangers walked into the party and, eyewitnesses say, walked out with a MacBook and at least one purse. My purse, to be exact. After I noticed that my purse was missing, three of the alleged thieves came back to the party, apparently hoping to steal more stuff. Partygoers detained one of them, who was then arrested by San Francisco police on a conspiracy charge. Good thing they didn't check out the back yard. For a glimpse of the scene, here's a gallery:
