I forget what Joel Sacks does, but he's fun at parties. Swing by XYZ after 6 p.m. tonight and say goodbye to the man before he leaves town for someplace where he can live down that beer-spilling incident.

THE GALLERY LOUNGE, SOMA — Joel Sacks of AdBrite wants to have a word with me. No, nothing to do with his company's adventures in serving up porn ads; he's still pissed off about the time we caught him on video soaking himself with a pint of beer. This time, he's dry. But he's just lucky — this San Francisco bar is packed wall to wall, thanks to social-news site Reddit's open invitation for anyone to come and spill a free beer on their neighbor. The largesse comes from Reddit's owner, Conde Nast, the publisher of Wired, which bought the site a year ago. I got to meet Reddit's founders, most of whom are still, contrary to rumor, at the company. But one was, notably, missing in action: Aaron Swartz, the obstreperous Reddit cofounder who quit shortly after Conde Nast bought the site. More on the founders' status after the jump.
