Goodreads allows their users to set their own preferences, so if you like crime novels or a specific genre, you are allowed to go into your settings and set it up that way. You can also click on the "My Books" link at the top of the page and create Book Shelves that will allow you to have the type of books you enjoy recommended to you. For instance, I have a Book Shelf that I created that is titled "Not Interested In Reading". Those books, if I go to the far right of the column and uncheck the "recommend" box, will no longer be suggested. I also created a "Favorites" Book Shelf that I kept the "recommend" box checked. You can set up unlimited amounts of bookshelves like that, and use them if and when you have read a book and want to review it.
