How important is this concentration for modern technology, anyway? Do flights to SF not make up for this in terms of meeting investors and other contacts? And sometimes I feel like the SF filter bubble is harmful. There are niche markets around the world called "cities not named San Francisco". I know that where I live, there are no good quality websites for local services or other keen initiatives. Many of the SF "Failures" could easily kickstart themselves in a town like mine, I think.
