So I just discovered a great idea from 2001. So stop me if you've heard this one.
Michael Schwern created a detailed proposal for a project called CPANTS. I have long felt that CPAN would be benefit from some kind of rating and comment system, and this sounds like a great solution.
Personally, I'm in. I'll help.
Read it and see what you think.
