I've lived in Austin for about 5 years. Grad school, not work. My programmer friends seem to have no problem getting jobs, and I have no shortage of male friends, but the gender ratio of singles is pretty heavily skewed towards men for introverted nerds. I'm a single male who doesn't have a lot of free time, so I gave up on dating in Austin. The city doesn't seem to attract many people I'd like to date. Particularly…
I haven't found that experience at all. In fact one of the reasons I refuse to move to Man Jose or SF is because I've heard of the famously skewed sex ratio. There is a lot more diversity in Austin, and as a single guy in his late 20's I've had a very healthy dating experience.
I lived in the bay area for ~4 years, lots of dudes, immigrants, and really wealthy people (in addition to a lot of the working poor). Interesting place just not my cup of tea.
Did make Buena Vista inspired Irish Coffees last night though.
