Why do I need to sign up? The "You are just a few clicks away from..." shows me that you don't have my best interests in mind. Please let me pick three books, provide a recommendation and then offer me to create an account.

Now I'm going to close my browser, get some sleep and completely forget about your supposedly awesome book recommendations.

Thanks, this is an interesting idea. I actually need more than 3 books to generate useful recommendations...more like 20 ratings. The other problem is that this is still beta stage and the algorithm to create your book list is very computionally intensive. It takes days not seconds to compute everybody's recommendations. The choice is between good recommendations delivered after waiting, or not that great recommendations delivered instantly.
