Yea the adage that you should move to the bay area to start a startup feels increasingly outdated. I couldn't have gone full time on my (now VC-backed startup) back when we were bootstrapping and living on $2k a month from early customer credit card swipes (one of the absolute best feelings in the world) if we had living costs like that in SF/bay area. Once we did find traction and raise we still didn't move. Times are changing.
Plus, doesn't pg say the most important thing is to just stay alive?
