The difference is that Reddit is even worse. It’s like a distillation of all the most angry indignant rage inducing crap from the other sites all into one.
I moderate my own subreddit, and it's definitely not "angry indignant rage inducing crap". That's the other thing: Reddit is moderated in a way that most other giant platforms are not. Of course the standards of moderation also vary widely among subreddits.
But all the big subs and even the moderately sized subs and even the smaller subs have become crap. I’ve (sadly for me) wasted much time on Reddit over the years. The type of comments I mentioned have become the default on every subreddit that isnt tiny and niche. It’s impossible to have a genuine thoughtful discussion on any non-niche hobby or subject without it being flooded by the kind of negative comments I mentioned in my previous comment.
