I wonder if it would be worthwhile to come up with a heuristic that takes into account the CPAN rating, the version number, the last upload, the number of uploads, the number of downloads, the number of modules that depend on this module, etc. to give people a better sense of "is this the module I should use?" CPAN ratings was supposed to be something like that originally, but I think it doesn't quite tell you enough about the module.

If someone did an algorithm similar to Google's PageRank where instead of links you use module dependencies, that seems like it would be useful.
