Contradicting someone describing their own experience based on assumptions and generalizations that may or may not have a basis in reality is pretty arrogant. How are you so confident that you can presume to tell that person what’s going on in their mind?

More generally speaking though, I do agree that comments probably tend to give people more of a dopamine hit than the content itself, especially if it’s long-form. However comments on HN often are quite substantial and of high quality, at least relatively speaking, and the earlier point about reading the articles often being a poor experience has a lot of merit as well. Why can’t it be a combination of all of the above (to various degrees depending on the individual, etc)?
