I think karma scores have a negative impact on sites, because they encourage people to post agreeable (or antagonistic), shallow content. Reddit is an easy example of this. There are 'karma whores', which just try to accumulate as many (or few) points as possible, on the site, which negatively impact actual discussion.

Hacker News tracks average-karma-per-post, which if it was the only metric available to the user, might be a good fix for this problem. You'd still get feedback on how people perceive your comments overall, but it couldn't turn into a competition over points.

Does anyone know of any websites that have implemented such a system?
