I'm surprised HN hasn't added a feature where if you start a comment with "I'm surprised" it asks you to tick a box to confirm that you're really sure you're contributing to the discussion.
Usually when I’m surprised about something, I realize that I am uninformed or out of touch.
I am strongly in favor of this. I would also like HN to implement a warning that your comment may be extremely uninteresting if it starts out with, "Unfortunately..." or, "Can we all just agree that..."
Also some of the snide comments beginning with “lol” and “I didn’t ask you”.
