Last year, Sam Odio set up a wiki for the event and someone also set up a Facebook group. People wrote down their contact info on the wiki, and then a bunch of us got together and ate some tacos and chatted. Then a group of us went to have drinks at some of the bars. It was pretty fun, so I think this should be done again. I'd be interested.
I'm probably up for it again this year. I live in Mountain View and helped coordinate last year's dinner which Larry mentioned. There's still 2 months until the event, so there's lots of time for someone to get something together. :)
