I've often pondered about the issue of what book to read (or listen to) next, and would love to have the opportunity sometime to set up an online community with that focus: media selection.

Now NetFlix has a contest to try to beat their recommendation system. I assume it's limited to using the single-dimension star rating system they use, so any other dimensions, such as aspects of movies, would need to come from elsewhere, such as Wikipedia or IMDB, for example.
