I would assume there's a decent overlap between tech types/programmers/etc and pilots. They have the money for it (GA is not as expensive as most people think, but neither is it cheap), and they have the whole attention to detail/"The more gauges the better!" attitudes that tend to work well with flying. There also seems to be a pretty good overlap between motorcycle riders and pilots. Find a middle aged man riding 10k+ miles/yr on a BMW or similar, and there's a very good chance he's a pilot too.
