I don't know any more. Even the small subs I previously visited for good content have turned into their own little echo chambers, along with a lot of drive-by posts because small subs get recommended in other people's feeds now.

In some of the hobby subreddits where I had good discussions in the past it's now just one big echo chamber of people parroting the same information around, whether it's true or not. If you want to participate you either need to toe the line of the accepted brands/methods/techniques or keep your mouth shut. Most of us just get tired and give up

Yeah that's really the issue with all social media. If you restrict yourself to just checking what friends post on Facebook, or what people you subscribe to post on YouTube, those platforms are pretty healthy too. It's when you go to the infinite content feed that sites become an issue.
