There is the saying "the empty vessel makes the loudest noise". This was part of the reason I eventually left Reddit, as I was getting sucked in to the habit of making empty meme-like responses to posts.

Some of the worst places for comments I've seen are on youtube - just the lowest effort ("who is listening to this in 2026?!") or the most obnoxious, or just misunderstood. Partly this is because of voting systems combined with large numbers of people. Partly because of bots I suppose.
