Wouldn't we then be saying that no comment is worth more than 10 points under any circumstances? I am not sure that is the proper behavior either. In this scenario a well thought out 3 paragraph critique would be limited to the same number of points as a two word quip.
I'd prefer weighting the karma by comment length until it reaches at least three lines, combined with a markov chain that recognizes vocabulary like that in the linked article and common among insightful posts.
Possibly. But right now many two word quips get more points than longer, well though out, responses. If karma really has no value (over the few point levels currently defined) I guess it doesn't matter. But I always assumed that in the future karma points would be used for additional features.
Perhaps the upper limit shouldn't be 10, but the total number of words in the post. So a two word quip, only gets you two points. ;)
