I would love to work there, but the rents look completely ridiculous compared to the rest of the country. I live in the heart of a wealthy urban area, and still pay close to a third what I would pay in SF. I am an engineer, so I could afford to live there, but saving would be impossible. It is a bit worrying that the tech community seems to be so irresponsible with where they choose to set up shop. Sure, an office in downtown Manhattan would be awesome, but is it really necessary for a non profitable startup?
