Thanks for your input!

Well, you can't actually review with text like you can on here and on a website like Amazon.  You can only rate it using a five-heart rating and I guess adding it to your "bookshelf" shows how much you like it.  But, with that said, I guess it fits better under Review than Shopping.  Because you don't actually buy it directly off the site. It redirects you to Amazon, B&N or Booksense.com.  So confusing, I know.  Thus my reason for coming here and asking!
