The podcast is changing feeds and after March 30th, 2013 the current feed will be deleted from talkshoe (and iTunes and Stitcher)…Matt explains why, and what you need to do to stay with the podcast.
Announcement! We’re moving feeds on itunes! Come along with us!

For listeners like me who positively do not do iTunes, can use http://feedflipper.com/ to convert iTunes podcasts into an RSS XML feed which can be subscribed to in your RSS reader.
Basically you get this: http://feeds.feedburner.com/PodcastWinterfellGameOfThrones
Thanks for the info!
