A small suggestion for the listing page, a Randomise feature!! Either simply a random ordening of listings under the listings post, or a Random Listing button in the navigation bar that takes you to one random listing at once. The greatest treasures are often those you don't expect! Especially since most people browse / search for things they know they like (Fantasy fans only browsing through listings with the fantasy tag e.g.), and thus missing out on a lot.
On a sidenote, personally I find the font of the information on the listing page a little too small. For the review quotes it's fine, but I think that the update/rating/recommended status could use a tad larger font.
