I have rated hundreds of books in Goodreads and it still gives me crummy recommendations. For example, other books by the same author, or just books in the same genre with high ratings. Always the same collection of classics or things I can easily find myself. I would much rather have a service which sees a pattern in books I have rated highly in the past and surprises me with books it thinks I will like. Does anyone know of an actually good recommendation service? Surely this must be possible with today's AI capabilities.
