The recent implementation of a -5 karma penalty for replying to comments that are at -3 or below has clearly met with some disagreement and controversy. See http://lesswrong.com/r/discussion/lw/eb9/meta_karma_for_last_30_days/7aon . However, at the same time, it seems that Eliezer's observation that trolling and related problems have over time gotten worse here may be correct. It may be that this an inevitable consequence of growth, but it may be that it can be handled or reduced with some solution or set of solutions. I'm starting this discussion thread for people to propose possible solutions. To minimize anchoring bias and related problems, I'm not going to include my ideas in this header but in a comment below. People should think about the problem before reading proposed solutions (again to minimize anchoring issues).
I agree LW in say 2010 seems an ok proxy for what it would be like. With one key difference, posting Main articles is much more karma rewarding than it was back then. Articles did get over 10 or 20 karma even back then
We should remember that we don't really care how many of the lurkers become posters. Growing the number of users is not a goal in itself, though I think for some communities it becomes a lost purpose. What we actually care about is having as much high quality content that has as many readers as possible.
I would argue the median high quality comment is already made by a 1000+ user. In any case the limit is something we can easily change based on experience and isn't something that should be set without at least first seeing a graph of karma distribution among users.
There's probably a corollary to Löb's theorem that says a community of rationalists can't add new members to the community and guarantee that it remains a rational community indefinitely. ... (read more)
