Your comment makes me think, I wonder if some of the problem is power imbalances and one off communication leads to bad faith communication being a better strategy.
For example, in social media the votes outweigh the replies 10 to 100 fold, and fewer people read the replies than the first post (especially on sites where it's an extra click to see comments).
Yet to your point, if it's iterated, that doesn't work as well. Of course this isn't just a technical problem, but I wonder if there's a way to weight high quality commenters similar to high quality posters, and if that leads to the virtuous cycle you describe.
