Awhile back, for MIX, Tim Aidlin and I built Flitterbook.  We liked it so much that we now have version 2, renamed Flotzam, ready for your consumption.  Lots of improvements, including a new UI, RSS support, Facebook notifications and complete configuration control. Also, check out the Silverlight-created video that is a screen capture of the application in action.  So, we'd love for you to go check it out, let us know what you think on the Flotzam forum and watch the Flotzam blog.
