pg, is it just a plain average as in "karma / count_of_comments" ?

Consider using an average over a median range, i.e. sort comments by the score, trim top 10% and bottom 10% and then compute the average. This basically ignores occasional flukes, both positive and negative. Specifically, it rewards for consistently scoring well (and not just once) and doesn't punish for an occasional negative score.

I do a minimal version of what you suggest: I discard the highest score, which amounts to discarding the highest 2%.
