It would be interesting to see karma-per-word, as well, as a kind of succinctness density factor. Although karma points are not equivalent to quality, and you’d need to also factor in average comment length and some other things.
To use myself:
31,273 karma / 351,012 words ≈ 0.0891 karma per word
A quirky feature of HN is that you can only see detailed karma counts for your own posts. One of these days I plan to scrape all of mine so I can sort by karma and do some meta-commentary.
Hot takes? Aside: an example of a "third rail" post (where I seem to get the most downvotes) appears to be when I disparage UBI. I used to get hated for disparaging self-driving cars too but people beat me up less about that these days.
