Getting a Book Recommendation

There are a number of sites that recommend music or videos, based on what you already like. Apparently someone has been trying the same with books. He had been pursuing a number of potential business partners for a year, but now apparently there is a real contract with a real client that will provide "a great deal of potential data to work with," rather than the 207 mostly science fiction novels that have driven the research. I wonder if everyone will be told to try Dune?
