I think it's hilarious that people equate immature postings with poor track times and no jobs. Since when does being a jerk make you slow and poor? I know plenty of immature jerks who are either fast, or make a ton of money, or both.
I'd also be willing to bet that most posters on this board who are 20 or older have had plenty of dates. You all don't seem to realize that, the personalities you see on this board are probably highly dissimilar from their real-life counterparts. It's the nature of anonymous internet activity. There are probably alot of jerks on letsrun who, in real life, are actually quite pleasant and even popular. I've made my fair share of rude comments on letsrun, but in real life I have alot of friends, am married, and people would probably never peg me as a jerk. Don't be naive. If you met alot of these "assholes" in real life, you would probably think they were quite the upstanding citizen.
