BETA WHAT SHOULD I READ NEXT literally addresses the "book" in bookmarking. Users are encouraged to manage lists of their favorite or most useful books (by entering a title, ISBN number, or url) and then group them into familiar categories. Other users may then enter one of their favorite titles and receive a list of other titles that may be worthwhile. It's not terribly different from an Amazon recommendation engine but the machine learning algorithms take a bit more human input. Think of it as the Pandora of publishing for beginner bookworms.
