This was mentioned by someone here a few years ago, but I still think it would be cool to see the karma/posts ratio for people. Just for kicks, not for voting (:

To be perfectly honest I never even notice the names on comments.

OK, not totally true, I notice pg and one or two other people that I know personally. I remember when hacker news started and pg would automatically get pretty much every member upvoting him (hence him not being in the leaders section- no one even comes close I assume).
