I can't see how many points your comment has and I don't think you can see how many mine has. All we know is that a majority of others have not downvoted our comments because they are not grey.

This breaks up the impulse to dogpile or blindly conformally agree. It asks users to think about their votes because it removes the motivations to be impulsive.

Points on individual comments aren't. But they are still ranked so in a way the effect is still there, just reduced.

Your point count is public. The score on your comments is not.
