I would like to suggest adding a further option under "Navigation options" in the listings: the ability to search the site by rank, i.e. 5 star, 4 star etc.
That way new readers coming to the site can find the cream of the crop with one click, and those high-rated stories that have dropped off the review page would be easy to find.
As a reader, I have to troll the listings, and there are far, far too many subsections to search effectively.
If you're going to have a rating system, why not use it?
