Probably because I haven't seen this analysis done publicly before. :P Comments are also much more difficult to systematically punish, probably because they don't get the same visibility as top-level posts do. I'm not so much interested in the reward, for a good comment, because to me, the endorphins and serotonin I get from having a genuine interaction with someone is the "Drug" I am chasing.

I don't want to punish people who make shitty comments, that would discourage them from improving. Instead, I think we should reward people who make good comments, and try to raise everyone's ability to create, good, engaging comments.

They don't even have to be in English. I'm seeing lots of other languages in the plaintext I've extracted, and I see a lot of "gracias", which I know means Thanks, or something :P It is just that English is the only language I know fluently, other than the various sounds I make when I bend over as I continue to age and lift heavy things at the gym. :D
