Sure, LA is in California but it is far away from SF and Silicon Valley that it is a different place. I speak from experience - I live in SF having moved from London in 2006. At the time I had a large offer from an LA based firm, a firm I later did a year's stint at by commuting between SF and LA. LA is NOT SF. If you move to LA you will have a ton of fun outside of work but you will still lack the buzz that is SF. Take a week's vacation from your job and travel out to SF for interviews and meet people. Hit me up (email in the profile) if you want meet up. You'll almost certainly get offers and that should be enough to prove it is worth moving out here for. The bottom line is that many startups won't make offers or even interview you unless you are here in the city and so you gotta be out here even just to plan the next move.
