check out Austin on the City Data forum:

I have been lurking on there for a couple of years...and am finally moving from London to Austin in April. I have found the City Data forums to be very useful and regulars are pretty helpful...a bit like here!

Good Luck.

Austin is definitely more liberal and diverse than other Texas cities. But Americans are still far more prudish....and they don't always appreciate the great British sense of humor!!!!!
