Reading Books and Sharing

I just registered on a site called Shelfari. Contributors create virtual bookshelves that display icons of their favorite books, then share their opinions and comments with other contributors and in discussion groups. It even has links that enable you to buy a book that you would like to read. I figure I will try to add a book a day. The site is still in beta, and has some glitches to work out, but I hope it catches on. Here is a link to my bookshelf: http://www.shelfari.com/TradeWinds/shelf. I have also placed a link in my sidebar for future use.
