Anecdata; I played comp TF2 for ~3 years a while back, won some negligable amounts in tournaments a few times.

Most of the people I played with were "Really Normal"(tm). While it certainly skewed aggressively the younger male demographic, most of the people were either students or typically blue collar, with a few programmers/other types of tech as you'd expect. I never noticed any sort of real similarity in the personalities of even the top players either; it seemed as much a "collection of normal gamers" as you could get from most other reasonably heterogeneous pc game strata.
