I've noticed the quality of LW posts varies greatly, even among top posts. Some of this is subjective or comes from what I want out of LW, but I suspect some posts are not nearly as useful or fun to readers in 2020 as their karma makes them appear.
Answers should be links to particular posts with more than ~75 karma that the answerer has a relatively unknown strong criticism of, or a general pattern (e.g. posts from LW 1.0 often have a higher score than they deserve because [reason]). Please give a reason why, and don't automatically downvote a post someone else links.
