Yes, reddit should honestly just be blacklisted from HN

Depends on the sub. Personal anecdote subs are the same yes, and not surprisingly they are very popular. There is a reason subs like /r/thathappened exist.

But there are good ones too imo that I follow, usually the more on-topic ones like /r/buildapc, /r/datahoarder, /r/networking, main sport sub like /r/soccer or /r/baseball.

95% made up, propaganda, or advertising for celebrity/product/brand/sports league/etc.
