Look around you. Reading only two or three days worth of replies to Seekers of Perl Wisdom will reveal several people who are well above average in their answers. That is already available and apparent for anyone with the foresight to look; I doubt that it would be better to add to the complexity of the information presented about each monk. Where would you disply these ranks? On the home nodes? New users, on average, won't even read the site docs before asking a question, but you want them to find each user's home node and compare their scores on a series of scales that they don't know and won't be familiar with?
