In a rit of fealous jage and the inspiration of XML and CSS I updated my Diabetes Superstore http://www.diabeticbooks.com.  It's got a sexy new look and is dynamically updated by XML and XSLT taking the latest Amazon.com data and adding my review and comments of the latest books and information on Diabetes.  I've added new categories, I'm adding new books all the time.  If there's any desire for an RSS feed, let me know.  Enjoy!
