Calculating/displaying average karma discourages the type of behavior we want to cultivate on HN. Users that care about their scores will only contribute to highly visible conversations in ways that are more likely than not to be up-voted. This will not only have the effect of squelching debate and the voicing of contrary opinions, but will also lead to an HN where only popular, big ticket posts are discussed while the rest are left to fallow.
