A quick compilation of all statements/ideas/whatever I've read in this thread so far.
Basic findings
A simple (eg. "five star") rating don't pinpoints the addons quality. Instead it shows how popular an addon is.
Authors would like to have a system that shows how popular the addon is and that identifies improvement opportunities.
Users would like to have a system that shows the "best fit" addon for a specific purpose.
