There also appears to be a non-linear effect where posts that reach a certain threshold of votes get even more votes—like there’s some kind of 80⁄20 power law at work. I can think of a number of possible explanations for that phenomenon but it would be interesting to see if the data backs up my impression first. I predict that the Gini coefficient for comment karma is > 0.3. Does anyone know a better way to obtain the data than a web scraper?
ETA: I’m referring to the Gini coefficient for individual comments’ karma rather than for individual commenters’.
ETA2: How to handle negative karma? I’d suggest ignoring negative scoring posts but other suggestions welcome.
