Exactly. I came to live in Boston because there is shit-all for tech companies in Jacksonville, FL. I wasn't about to start one for myself, and I wanted to both make a good salary and get lots of experience. If you want to work a job, you go where the jobs are - and those are in places like the Bay area.

Of course, none of this would be an issue if we would all just work remotely, but that's not going to happen for a while.
