* HN Companies and sock puppets pushing agendas
* Hacker news counter culture movements and backlashes. Seems to be bipolar with pro Rust / anti Rust every day of the week.
* Hacker news nice guys who have account names like "mothsonasloth" or something really depraved. Along with all the other hypocrites
* Hacker news Admins and big personalities driving content trends on the site e.g. (/u/patio11)
* Recycling of posts / knowledge, since there are always new people joining. You get things like "TIL that microservices are awesome" trending once every month. Which is frustrating for veteran users
* Hacker news arm chair generals/economists/politicians. The points system rewards trendy content and doesn't necessarily mean quality. Unlike points in Stackoverflow, there is some degree of confidence in the users competency.
* The fact that Hacker news is mainly populated with technologically proficient people, who probably have some sort of issue, whether it be mental, psychological. Sure we all suffer from our demons but the amount of stuff I read on there makes me cringe at times.
* The "Hacker news Contrarian", waiting to snipe your post with their immense intellect
