I find reddit, for the most part, is they are trying to pretend they are like 4chan, where you can say and post anything, while also being like twitter with heavy censorship and bias. So if 4chan and twitter had a kid and twitter divorced and got sole custody, you would get current reddit. Some communities are ok though, but these days it is mostly people being angry and raging about things. like take runescape reddit, and DotA 2 reddit for example, it is mostly people hating on the devs than anything else.
Although this is my heavily biased opinion. I personally think discord is now king. and well 4chan is as always just being 4chan.
