I would suggest that you search on MeetUp.com and look for topics that interest you like Ruby, PhP, Opensocial, Iphone, etc .... 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.
