Put some teeth into karma. Make more karma mean bigger upvotes and downvotes, say 1 extra point for every 500 points of karma. It doesn't have to be linked to when a person joined. It's elitist like a journal or university, but at least anyone can read HN, and good posters will rise. Problem solved? EDIT: Oh yeah. 1 week comment lockout for negative karma, with a grace period for newbies to learn how to comment.
