I would recommend Austin as well. There are loads of developer jobs here, though I don't know any particular place that is hiring right now. We have an active, close-knit rationalist community that I think is pretty fantastic. Worth consideration.
I was going to make a plug for Boston, but with SAD, someplace with a sunny winter like Austin sounds like it might be nicer.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
