I'd say that all of the above have become more refined, but I was always different than my peers growing up so they were a bit more refined to start (in large part due to more reading and different media consumption).

My interests are very much middle/upper middle class geek though and that's definitely something that the upper classes aren't very comfortable with. I'm not interested in a lot of the thinking that comes out of high end private liberal arts schools for instance. Really a focus on math/computers/science is generally not an upper class thing. I like media but not "art".
