I've been doing some thinking (uh-oh)...

Although there is a considerable amount of effort put into an answer, good questions should always deserve a fair ammount of XPs. If there were no clue-less monks in search of wisdom (such as myself), there would be no use for this site. Come to think of it, the term monk presupposes that one is in search of higher enlightenment.

Rating based on signal/noise (as you put it) might discourage the ardent to pursue knowledge monks. I suppose only the higher saints should be listed in a signal/noise ratio, while the rest of us mortals be listed by XPs...
