Didn't know about the Culver City expansion, neat! There's a tremendous amount of tech talent in LA, I'm surprised they don't already have a major presence here
I live in LA and I think the level of tech talent is abysmal. At the Java meetup this week, eight people showed up. EIGHT. In the Bay/SF/NYC, there would be over a hundred. I have been to tech gatherings, where I would be the only techie.
I get recruiter emails constantly from companies in SF, Seattle, NYC, etc, but rarely from LA. There are simply not enough companies doing challenging work. Many small little startups trying to solve problems that do not need solving.
