I'm looking for a good user-submitted reviews / ratings plugin for a Wordpress Site that I'm developing which serves as an index of Hotels and Restaurants for a popular resort town in the US, -- ideally one that provides a review format that Google prefers and ranks the highest.
I'm clueless as to what Google actually ranks the highest in this context, .. but I'd like for users to be able to post a review (without having to log in) and assign a rating of 1-5 by clicking on little star icons (similar to how they do it on Amazon). It would also be great if the reviews could be held for moderation when submitted, .. which would require that an administrator manually view and approve/publish the review. Something that plays well with the Askismet Wordpress plugin would also be nice.
I'm thinking that something that leverages the native commenting functionality within Wordpress would make the most sense, .. but I'm open to using something that's entirely separate from that if it does what I need it to. Does anyone here have any suggestions?
