I agree with this, but the point of these user interactions is to whittle them down to something that others can easily relate to. If you then say "well people can agree/disagree" with comments, then we're back where we started. Why are they agreeing? Do they find it funny, useful, or just like the way the user makes their point? How MUCH do they agree? What if they disagree? If your reaction is that we should completely kill these interactions then... well have you ever been on giant forums with no way to sort? Sometimes they're fine. Like when there's low volume. Some forums evolve chronologically and that method works as well. But if you're not gonna commit to reading a pamphlet, you're probably not gonna find such a comment section very useful
