The population of commenters seems to be dominated by those whose goal is to argue and win, rather than to understand and learn. So many times I see comments that make no attempt to take context into account, and instead conflate all sorts of things, making it impossible to comment productively. (Basic example: Top comment has not replied to the thesis of the article, but to something else.) When one of these types of comments is at the top of the comments list I just hide the whole story, because there’s literally nothing to see but people talking past each other.
