Suggestion: ratings for projects

Before I try a module or theme, I usually check the Issues list to see how stable and/or well-supported it seems to be. But user ratings of people who have tried the projects would also be helpful. It should also be possible to change one's rating if the project improves. Maybe the ratings could be tied to comments on issues in some way. Even just rolling up some basic statistics to the project page, e.g. number of bugs, issues, & feature requests, and mean time to closure of bugs, issues, & feature requests would help.
