LA CTO Forum Dealmaker Media Digital Family Reunion Startups Uncensored Social Media Club, LA Twiistup Mindshare LA LA Hadoop Meetup Dorkbot Geek Dinners LA Cloud Computing LA Web Application Developers LA PHP Developers In addition to these, I'd recommend looking at: Technology Council of Southern California – Surprised John didn't mention this one.

LA Web Developers LARTA Rohit Shukla, LARTA Howdy Campers! Digital Family Reunion is bringing all of the LA Tech/Business/Media scene together next month, for a nice holiday party at the Skirball Center!
