What Should I Read Next?

Let's imagine that we do not have those piles of books under the "I will read those next month or next summer" headings and we have just finished a book we enjoyed without knowing what to read next (I really doubt that could happen soon) but let's just pretend... How could we find something similar to what we have read, imagining that we would like to read a different author, and not the one whose book we finished... Clever people thought about this and this wonderful site was created, WHAT SHOULD I READ NEXT?, which can recommend you different books based on your reading(s). You can also create lists, share them or even buy those books from Amazon. Is there anything else missing? let me know :)

P.S. Unlike The Book Seer which cannot offer any recommendations and tells me that I should stop reading books (loool), What Should I Read Next? actually works :)
