I've gone back there from time to time because there's not the specialised subs here yet, or those that are don't have the traffic.
What I've found on the main dubs I used to frequent is that they are full of reactionary comments that have no grasp of history, context or empathy.
The specialised subs, maybe were like this and I was just more tolerant to it, are full of low effort "please look at me doing absolutely fuck all in any way of producing meaningful content" posts.
There's far too many to actually get to the content with effort so the signal to noise ratio is too low to fight off my general contempt of the place.
