One of my users has mentioned a problem in downloading your podcast.
http://www.pocketpcthoughts.com/xml/thoughtcast.xml
It looks like the problem is the URL attribute of your Enclosure element. You are not including the ".mp3" extension of the file, and RSS Aggregators cannot find the file.
Once you correct this problem, FeederReader will detect the changes and should update each message seamlessly.
