 What our algorithm does is sort them, so the ones that come at the top are the ones that we think you're most likely to want to read. And there are issues around that, how we select what you will find most interesting. But again, fundamentally different in that some of the criticisms that are being voiced and the challenges that are being presented to us are not necessarily about the algorithm ordering that set of books, but the choice of books that you have made in the first place.
