I've read quite a few writeups recently with the same general topic: How do we focus on the signal and ignore the noise? After long thought, about 30 or 40 seconds, this occured to me... Perhaps an eBay-like "rating" should be added to the author's name.
That is, for any given monk, take the average reputation for all his/her nodes with a +/-reputation (zeros excluded by default):
In the case of someone, shall we say, less than useful, there'd be a big ol' void where the "stars" would go.
In the case of someone somewhat useful, you'd see: by a_useful_monk *****
In the case of someone useful, say, vroom, you'd see: by vroom **********
This could be implemented via perl's x operator.
