Goodreads says it is the world’s largest site for readers and book recommendations. Unlike Amazon its sole purpose in life is centered on books.
You can see which books your friends are reading, and be surprised that someone who hated English in High School now loves the classics, or that man’s man, he-man football and NASCAR loving friend, reads Harlequin novels. :-D
You can track the books you’re reading, have read, and want to read. You can check out your personalized book recommendations, tailored to all sorts of interests. You can not only rate a book you have read, but write a review.
