Just a random thought - what if there were a spot on each monks home node to list the 5 (or 10, or whatever) CPAN modules that they use most frequently?

You'd get a good idea of what are 'good' modules by looking at the more experienced monks' nodes.

It would also be possible (I suspect) for PM gods to pull some kind of weighted report out of all the home nodes...

Participation would, of course, be completely voluntary. :-)
