I've been trying to participate in StackOverflow but keep getting messages about how I need "more reputation points". The only way to get more points is to ask questions, which seems kind of dumb. Wouldn't you want to reward people for answering questions?
Anyway, it would be nice if users that sign-up could bring over reputation from other tech communities like Hacker News or github or better yet, change your reputation system so people like me who want to help by adding comments can do so. Maybe you could start me out with 20 points and if I make dumb comments that get down-voted, I loose my commenting privileges.
