At random intervals, an event called Nerd Salon happens in San Francisco. People meet at a bar, drink, play with robots, and have a chance to solve a puzzle to win something cool (usually alcohol). It's organized by yours truly and Jennifer Granick, a kickass lawyer (and serious comic book geek) from the Electronic Frontier Foundation. A new installment of Nerd Salon is happening next week, just in time for all the web nerds in town for O'Reilly's Web 2.0 Expo, and of course io9 readers are cordially invited. Come out Wed., April 23, 6-9 PM at the Makeout Room in San Francisco. Get drunk and play with bots. And talk about aliens. Or zombies. Whatever.
