Seattle isn't too far behind SF with regards to housing (according to recent press at least). I've been wondering for years: could the larger employers in SF do more to coordinate which cities are expanded to? I'd be willing to change locations if my (tech) employer gave me the option, but others might have concerns about putting 'their eggs in one basket'. If 10 SF based companies all opened an office in the same city, would more people consider the move? My hunch is yes and I'd love to see this theory tested :)
