Does the Dallas story (low demand for devs, high availability of devs) line up with the experience of those here familiar with the market? Based on just looking at job postings, it didn't seem like there was a lack of demand for devs in that area, but I know that postings don't necessarily equate to high demand. Also if that's true, do alot of the Dallas devs in need of work go to Austin? Or is that not done for some…
As far as Austin, no. Only reason people go to Austin is more a lifestyle choice. More people come from Austin to Dallas simply because the number of available jobs. Last time I checked, Dallas has around twice as many developers as Austin as well.
Right now, people in Texas cities other than Austin are staying away too. Austin's infrastructure has not kept up with the growth and it is nuts. Dallas and Houston have done a much better job when planning ahead for the growth of the entire job market, whereas Austin took somewhat of a Boulder, Co stance and decided they really don't need to work on infrastructure to aid growing the population. That's a whole other story though.
