The growth in Austin is pretty crazy. I was there a few months ago, about two years after my last visit, and things were markedly more crowded. I remember thinking "I can't wait to get back home to get away from all this traffic".
For those looking for a smaller city and/or more conservative city than Austin, check out Bryan/College Station 90 miles away. BCS is home to 50,000 students at Texas A&M University and also TAMU Startup Aggieland.
If any HN'ers are in the area or interested in the area, feel free to email me (contact info in my profile).
I worked a few months in Byran/College Station for TEEX. It is one of the nicest places I have ever been! the people are extremely friendly.
I like Texas a lot, and lived there (in Harlingen near the border, and Houston too) for a while, but College Station takes the cake for nicest people all around and a great place to live!
Strangers in the street literally greet you with a big smile and a 'Howdy'. :-)
As a long-time veteran of DC traffic wars, I have to say Austin is rapidly catching up in terms of pure automotive misery. It's horrid. Geography plays a cruel trick there (the river combined with the environmentally sensitive hills to the west), and it's only going to get worse.
I live in Los Angeles.
