Social Networking for Books - Shelfari

Not a great idea! Social Networking has been an important ingredient of Web2.0, and everyone is cashing on it. Everyone wants to have a finger on the pie.
Shelfari http://www.shelfari.com from Amazon is a Social Networking Site for Books. One good feature is, you can generate code from Shelfari and copy paste into your blog to display the list of your Books.
I had registered mine, hope to place the code onto my blog as I get time.
