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.
I'd like to see projects like this work, particularly because I haven't always been pleased with the recommendations from Goodreads.
That said, your site's going to need more information about why it's any better before I sign up for an account. What genres do you cover? How wide is your database of books? Is it possible to offer a trial w/o an account? E.g., enter some books and get recommendations -- and then ask if I want to create an account w/ these settings so I can continue to get more recommendations?
I really like the idea of a more content-based approach to book discovery. It feels like a complex problem to me, since there are so many dimensions one could pivot on; and how to find them in the first place? As an example, I dislike first-person books even if they might seem like really good fits for the kinds of topics I read. There's also a clustering issue around "well, I like sappy space opera when I'm on vacation but more cerebral fantasy epics on the train". But good luck with solving that.
