I read HN comments as a filter. If I am interested by the article's title, I go to HN comments. There, I sense if the article is useful and/or interesting. For this purpose I like TL;DR and quotes of the article in the comments. Also compliments and reassurances that the article is indeed good. A the other hand, good critics showing that the article might contain fallacies, is superfitial, is clcikbaity, etc. make me lose interest. Even when I am pretty sure I will enjoy an article only by the title and source, I open the article in one tab and the HN comments at another (so I can read the article, but also what the comments might add to it too).
