Last night's io9 meetup in San Francisco was incredibly fun and well-attended. We've got a giant gallery showing science fiction nerds in their natural habitat: Borderlands Cafe, among giant bookshelves full of paperbacks.

If you don't see your name in the captions, pipe up in comments and tell us who you are! Or if I got your name wrong, let us know about that too. Thanks again to Borderlands for being such gracious hosts for the event!

io9 book reviewer and Borderlands employee Chris Hsiang (Grey_Area) makes a point while io9 commenter CrashedPC laughs. I can guarantee they are both going to give me crap about making this the top picture.
