Best networking venues in SF to meet programmers
catch23: Hah.  Don't waste your time on any of those...  You'll probably meet the wrong kind of "programmers" at those events.  I would say stick with the language meetups (Ruby, Python, etc) and attend SuperHappyDevHouse.  Also visit coworking facilities, you might find interesting people there as well.  I tend to meet some of the brightest hackers at coffee shops, but ymmv.
