Thanks for your thoughts kth. If there's not much of a response, I will try posting again, and indicate a more focused purpose for the meeting.
In fact there is a New Tech Meetup every first Tuesday of the month near DLA Piper, Palo Alto. They have about 3-4 demos by hackers/founders followed by networking. I have easily seen 150+- people.
Recently I've been making an effort to talk to more people (offline and real conversation) instead of being holed up in the CS lab coding all the time and its amazing how positive of an effect its having on my mood and creativity =)
