I’m keeping an open mind regarding the new Microsoft RSS Platform introduced in IE 7.0. It will be a standard component of Windows Vista.  I’m perfectly happy having the OS maintain the feeds store and helping with synchronization and letting applications focus on the display of content.  After all, the SocialDynamX software never was a true RSS aggregator.  It basically served as a consumer of a service, just as Microsoft is suggesting applications do in their new platform.  The service in FM Radio was the local Userland Radio server running on the PC.  We simply picked up the data locally from Radio using XML-RPC.
