Since there is now a duplicate for showing the percentage of answers that were marked as the accepted answer like we see for the questioner's acceptance rate, I think that we should show a percentage for the number of questions that get closed. We could then break that down by the different close reasons.
We could expand this even further to modify the avatar to put a dunce hat as an overlay or something.
We could also show the percentage of posts, comments, etc. that are flagged for moderation attention.
Ok, I vote NO for all of the above...
