Hmmm, well....I have soem friends/aquaintances who are geeks. By the population at large I am probably considered to be a geek. By the aforementioned guys, I am nowhere close to being a geek, since I don't know any programming languages or anything more than HTML.
I suspect that at least two of those guys are aspie, however I also know that at least one of them is not, and he's a pretty serious geek.
He:
is not averse to sitting in a stadium full of people watching a ...what do you call the event where old beat up, armored cars race and crash into each other? The cars make a LOT of noise.
Says many polite things that he does not mean at all, simply to be polite.
Cares a great deal about his personal appearance, vehicle, status symbols, and actively nurtures these things.
Makes prolonged eye contact with people, even people that he is not close to.
Takes pains to attend to family duties, for example, visiting family he hasn't seen in years, becuse he wants to get to know them or because he thinks thye would like to see them.
Has very little comprehension of the sort of obstacles and hang ups that plague an aspie- phone calls, going into strange places, breaking out of a negative cycle, etc etc. He simply cannot understand why any of these things are an issue at all.

I think those are some of the differences. The same question has occurred to me, by the way.
