I'm not sure if I'm surprised that dang didn't touch on to mention downvotes as an even more rapid "contrarian dynamic" mechanism; wouldn't it be nice if downvotes had a little more friction, effort required for the action - like qualitative text from the downvoter as to why a comment is being downvoted to then allow OP the opportunity to clarify or expand on their comment - "to be more reflective and therefore better written"? The downvote-comment doesn't have to be identified as being a downvote-comment, showing up as a regular reply.
That added cost/friction may also act as a filter for lazy readers/skimmers or those misinterpreting what's said at first glance, and therefore if forced to include some critical text response along with their downvote then OP and other readers can begin to get to the bottom/foundation of the distaste, giving OP at least some guidance as to why someone/people are downvoting - arguably a valuable learning/crowdsourcing moderation tool/mechanism.
I feel the added cost of time and mental effort for downvotes would add a great balance.
