After Reddit's API fiasco 2 years ago, things started to degrade really fast. Today, everything is more bland, less insightful comments and more aggravated/toxic comments. I mostly visit due to habit and mostly I feel worse afterwards. It wasn't like that.
Even on communities like r/woodworking, which used to be a bunch of nice people. I mean, how can you be toxic and a woodworker at the same time? Sure, occasionally you'd get someone that hammered his thumb but that was the exception.
