Yep, here is another interesting site I ran across, and if you are a self-published author, this is a place you definitely want to visit.  I had quite a bit of fun once I realized what the book widget did, and I can tell you that it's a wonderful way to promote your books.  Yeah, I know that I say that about a lot of sites, but I promise you that once you see what this does and realize that it's FREE, you will definitely be visiting that site again.
