Every thread is a rehearsal with same opinions at the top over and over and non-fitting opinions float to the bottom. In which turn, they get less "downvote-power" so they will stay low and can't get their peers above. I am not saying that the current flow of discussion is bad, I am just saying that participation is flawed.
We are simply in a system where you get awarded to fit to the masses and you get more power once you have been accepted into the hive-mind. A circular-reference at some point.
