I'm an io9.com fanboy. I wish that the discussion there didn't revolve around their culture (though, I guess maybe that's the hardship any internet-foreigner feels). I just feel like a lot of real discussion doesn't seem to happen there - which is funny because I definitely intend to put them on my resume one day (some of them actually get paid to write - not so strange given the depths of the articles vs. the plebletariot).
