What's tech's obsession with the bay area? It's lovely, I've visited - and then left. I can see why companies would thrive in an area with this excellent skill-pool - but I'd have thought they'd all want to get their employees out of there as soon as possible, once they'd got them. Chuck them into a new office in the mid-west, let them buy a 5 bedroom mansion for a fraction of their salary, and make potential poaching as painful as possible. Only possible reasons I can think of for what's happening are: 1) Insanely rich bosses are delusional, want all their staff around them, and the 'prestige' is over-riding sanity. 2) Staff consider Bay Area is "making it" and are happy to flit between local employers, ranking up their salary as they go.
