There is a critical mass effect: If the average reader of my comment is smart, I don’t get away with ventilating my anger; it’ll just get pointed out and downvoted. So I might as well behave.

And there is a no-duplicate culture: If I have a point that I want to make, and someone always expressed it in a comment, I just upvote.

20% of my comments are discarded with the interrupt handler in my brain going “Wait, is someone wrong on the internet?” Hitting Ctrl+W just discards the message. It’s a feature for letting go.
