Are you most worried about snarky or rude comments occasionally getting upvoted, or the seeming proliferation of content-free comments? I ask because the rude/mean upvoted comments, though disturbing, are thankfully fairly rare. The content-free comments, on the other hand, seem to be becoming more frequent and less downvoted. Do you think the problems are distinct, or do they both follow from some other change in the community?
