Goodreads

Goodreads, a social network devoted to all things books, is smart for developing a Facebook Timeline app. For one, most of its users are already on Facebook, and secondly, anything that can be done to promote reading is fine by us. The Goodreads Timeline app will allow you to display what books you're reading and what books you liked. We won't say anything when Suzanne Collins shows up under your "most read authors list."
