I'll be honest, I'd like this - it would tell me (us) when others make better comments and help me (us) to improve my (our) own commenting.

It would also give readers an idea of how popular the ideas in the comments are - and perhaps, if we could show total up versus total down, whether the comments got a lot or a little attention.

This could be a privilege for those with high karma levels, similar to the downvote.
