Create Module ratings

With the HUGE amount of contribs, its hard to find quality modules. My proposal is to add a simple rating system (fivestar??) to get a quick idea of how other site administrators view the module. It could be attached to the module as a whole or by module version.

A more complex idea would be to create reviews for the modules themselves with actual comments. I would see this as more troublesome when users write reviews that could contain software problems that should belong in the issue queue.
