When I wrote my trip report, I lamented that the old DisneyCentral (aka Mousebuzz) Rate & Review had gone the way of the dodo and some old timers agreed with me. It used to be a place on the site where you could enter a review on a specific thing at WDW, and they would all be grouped together.
Um... somehow I missed that Allears.net has one:
AllEars.net Review Page - Main Index - Powered by ReviewPost. It's not perfect, but if you are looking for reviews on anything at WDW (and even things outside WDW) there are loads out there.
