Nearly every forum is like that. It may even be related to Dunning Kruger, in that people who overestimate their knowledge are obviously going to feel knowledgeable on more things.

That said, Reddit is probably the worst place for it. I rarely read comments anymore there because of how 'dumb' they are. Worse, I feel like Reddit is like some self trained botnet at times. Go on any post, say 'blood is thicker than water', and without fail someone is going to tell you the original is 'blood of covenant is thicker than water of the womb.' This is of course incorrect, and the only place I've ever seen it is...Reddit. So people posting ridiculous things learning from people posting ridiculous things.

It happens here though, too, with the main difference being someone will usually correct you, and not be downvoted for doing so...
