For those of you who like to read, I suggest goodreads.com. You create an account for yourself, then enter titles of all the books you can think of that you've read, and rate them. As you find other people you know who have a goodreads account, you will be informed when they start reading a new book and what that book is. You can see their ratings of books they've read, which gives you ideas about books that you might want to put on your "to read" list.
Also, Goodreads will suggest books for you to read based on what you've read in the past.
If you have an account, be sure and add me as a friend. The more people you are connected to, the better it works.
