There has been discussion about this on meta SE, but I want to ask about it here too. Comments do not serve the same function on all sites on SE, and this leads me to wonder if this sort of 'one size fits all' approach is really the best way. What works on SE might not be the ideal solution for smaller communities about foreign language.
The current rationale seems to be that good comments can get upvoted, and that comments that are bad, too off topic, or otherwise rude or offensive should be flagged for removal, but I feel like there's enough gray areas where a comment might not necessarily be a candidate for removal but still might display characteristics that the community wishes to discourage. At present the only real option is to leave a comment or call someone out in chat, but leaving more comments can derail discussion and callouts in general are prone to creating site drama.
So how do we feel about comments here on JLSE? Does the current model work, or would we be in favor of the addition of the comment downvote?
