Cap the score that is displayed with a comment e.g., past 10 points, just display "10+". Don't display karma and average scores of users, again, past a certain point: this prevents (subconscious) game incentives which lead to e.g., posting comments that say something stupid or mean but which tend to agree with general tendencies of the site.

For example, I can post a comment decrying Blub with a snide remark (e.g., "You wrote a 1,000 line Blub program? Was it 500 getters and 500 setters?" in a thread discussing software projects) that is both information free and mean (perhaps Blub wasn't the author's preferred choice, but chosen for him or required in order to build an application for the iBlubber). People on this site generally dislike Blub, so the comment will get upvotes without adding any value to the discussion (an example of adding value would be saying you were able to do this in 100 lines of Flub using its cool new hygienic macros with a link to a paper on hygienic macros in Flub).

That's not to say all comment score data should be gone. Comment scores can still be kept and comments could be displayed on stories in the other in which they're displayed now (a mix of comment score and how recently it was posted). Generally, what I've found is that comments showing up _first_ tend to be of higher quality i.e., overall algorithm works more often than not.

[NB: I work at LinkedIn and we do this for connection counts-- we want users to network with each other, but we don't want to make it a "who has the most connections" game, that's why when you have over 500 connections (which is perfectly legitimate and allowed), only "500+" is displayed as the count on your profile]

You, and other users both in this thread and in similar ones before it, are only looking at one side of the equation.

The problem is only partially too many bad comments, it's also too few good comments. Your proposal is targeted at lowering the amount of bad comments, but it might do so at the expense of the good ones.

Most of the users that have a high karma count have so because they always have something insightful to say (mechanical_fish (http://news.ycombinator.com/user?id=mechanical_fish) is a good example), and their incentive for posting interesting stuff is marginalized by this. Almost all people, whethere they'll admit it or not, are incentivized by other peoples approval, eg. karma, and downplaying their contributions will make them more prone to not submitting great comments.

One way around this could be through badges (a la Stack Overflow). You could automatically get badges based on average comment karma and so on, instead of tying your contributions to the HN community to a mere number.

That way, you're rewarded when you contribute meaningful, valuable comments, plus from a reader's point of view, your comment will still have 10+ votes.

I tried badges based on average comment score (the infamous orange dot experiment) and everyone hated it, including me, because it divided the community into haves and have-nots.
