Have you worked in the bay area?
Physically no.
I've telecommuted for a few contracts and the structure of those companies appear to be similar to what I've been exposed to here on the east coast.
I would imagine both have their fair share of differences and being there physically is, I'm sure, much different. However I find it hard to believe that the difference is so significant that it warrants surrendering financial gain.
I guess I was lucky enough to land a public sector job at a software shop that runs much like the hip ones out west. They are here, just not well represented.
