I've just run across this module so forgive me for bringing up an old topic or anything but I think it would be great to be able to see the number of users who have given ratings and some more detailed information as opposed to just the color scheme.
It's great to know a site is red, but is that because 3 people thought it should be, or 500?
Re: the number of site ratings
That's why the add-on has confidence indicators for each rating component. When users can rate websites anonymously, the number of ratings doesn't necessarily tell you how much the rating can be trusted. However, the confidence indicator also takes each user's trustworthiness into account and tells you pretty accurately how reliable the rating is.
