I'd say there are probably quite a few people that post to Show HN just for peer validation. Sure the constructive criticism is helpful to improve the project, but comments like: Change the colors, my eyes are bleeding. Or: Ugh, another Bootstrap site? could be worded in a more positive fashion while still delivering the same content. Even examples like: Doesn't work in Firefox aren't useful, because there's no mention of the Firefox version and/or the operating system.
