All the above mentioned projects (reviews, etc.) are great, but the require hardwork from many, so might be difficult to be successful(of course, there are counter examples: wikipedia). I'm thinking that just a simple vote-like page might do the trick, say a page in perlmonks so that any logged in user can put in the modules they use (and like to recommend), this will produce a list based on usage. This might work, since we monks all manage to find time for the Voting Booth after all. Of couse, someone needs to do that work also, damn, why isn't any good thing free.
