This list counts all time; the period switch above only changes the ranking. Each issue is a group of similar complaints raised by at least 3 people in 3 different months and threads. Each line under an issue is Claude Haiku's summary of one of its latest comments, not a quote; follow it to read the comment on Hacker News.

Unreviewed issues were grouped by machine: Claude Haiku labelled each comment as a usability complaint, named what it's about and summed up the problem in a line, and a small model grouped similar problems. Nobody has checked them by hand. Expect mistakes.
