My experience is either inside academia or way the hell outside (people who didn't go to college.) I never met an entrepreneur.

My experience with meeting Europeans is that smart people do have less of a geeky self-image than they do in the US (I've known Italian women mathematicians who look and carry themselves like movie stars) but that just about everyone in Europe is less into gorilla-type masculinity than men in the US. So I think your point is probably more relevant on the female end -- European female geeks are more conventionally feminine because they don't see a dichotomy. (I've also noticed that about Asian female geeks -- that is, raised in Asian countries, not Asian-American.)
