It looks really good. Seems like a great concept and good design. One suggestion I would make is have something about the app on the front page such as a video demonstration or a slightly more detailed explanation of what it does.
Maybe just a paragraph above the part where the random reviews appear.
We're working on a video that will explain the usefulness of the service, like someone having to aggregate multimedia content for a specific purpose and using it. But probably a simple description wouldn't hurt.
