I'm not a fan of the introvert-worship on HN and related sites- I see it used as a crutch, an excuse, a softer form of the typical claim to having Asperger's to explain how you can't talk to people. Not saying Asperger's or introversion aren't real problems, just that you can make yourself feel OK sitting inside all night by putting a label on it and talking about it on the internet.

I'm not quiet because I'm an introvert, I'm quiet because of past personal failures wherein I didn't learn social skills because I was dicking around with books and computers all day. So now I'm a loser, but at least I can admit the truth rather than wrapping it in pop-science.

(Btw, clearly the OP is not a case of this - just a related observation)
