World's Largest Bookclub?

Ever heard of this fascinating idea?? BookCrossing is a network that facilitates "the practice of leaving a book in a public place to be picked up and read by others, who then do likewise." All you have to do is grab a book that you deem so good that you want to release it to others, register the book on their website, and then accidentally 'forget' it on a chair in your local cafe. When you've found a book (you can check for locations on their awesome website), you are encouraged to write a journal entry about your finding(s), and the person who registered that book will be notified by e-mail where abouts in the world their ex-book is.

I found out about this via my neighborhood community forum, and was so excited about it I registered right away!
