I would like to propose a small change to the commenting system: Don't shade downvoted comments grey.
I've noticed it's like a snowball effect. I've commented on a post and for hours it wasn't downvoted or even upvoted. But as soon as one person noticed that it had been downvoted, it would get 2 or 3 more.
And I've noticed this impulse in myself. I feel much more compelled to downvote a comment that is already grey than one that isn't, even though the grey one may be a perfectly valid point.
Maybe a good idea would be to only show it greyed out after 3+ downvotes. That way people wouldn't have that knee-jerk reaction to downvote just because someone else has.
