There's a ton of great places: Seattle, Raleigh-Durham, Boston, L.A., DC beltway, etc. but I kept coming back to Austin. They've got so many things you would want: low cost of living, low regulatory burden, friendly community, lots of parks and open spaces, great nightlife, ease of travel, and so on.
When I look at the bay area, I wish them the best. They're still hands-down the best place to find money. But not so much in my mind of places to actually live. If I had a break-even startup and just wanted to live somewhere that I was surrounded by great talent doing cool things? I'd choose Austin in a heartbeat.
Although it's a close race, in my mind over the last few years Austin has moved to #2 in the startup world stateside. And it continues to improve.
