I'm not in SV (Seattle instead), but I'm already tired of "work parties". For once I'd like to talk about something other than vim vs. emacs, Android vs. iOS, Python vs. Ruby, etc etc ad infinitum.
The homogeneity of this environment is aggravating. It takes a lot of work to break out of it. I'm not sure what it is about geeks, but much of our community seems to take pride in being about tech - and only being about tech.
