Wow, this interferes with key elements of my system for voting/commenting on HN. Here are some things that don't work now: * If a comment is sitting at 1 or 0, I'll try to avoid downvoting it unless I really think the comment subtracts value from the site. * If a child is attracting more votes than the parent, and I think this is because the child commenter didn't comprehend what the parent was saying, I vote to leve…
Voting patterns showed a lot of users voted to get a comment to what they felt was an appropriate score: they wouldn't up- or downvote something unless they felt its current score was too low or high respectively. But if comment scores aren't displayed, you won't need to anymore.
I can see ways hidden scores may work for or against extreme totals. On the one hand, without the satisfaction of seeing a vote take immediate effect, overall voting may go down. But on the other, without the indication that a comment is already 'far enough' in a desired direction, charged comments may rack up unprecedented positive or negative values. I hope you can share info about which effect predominates.
I will miss the chance to quickly 'rescue' slightly-downvoted comments I don't particularly like or agree with, but feel have been unfairly squelched into nether-ratings by hair-trigger down-voters.
