One of the things that has annoyed me about the podcast functionality on the Zune is that I could not find an easy way to unsubscribe from a podcast from the device.
The post from Kevin @ jkOnTheRun about sharing and subscribing to podcasts (which I just posted about) from the device gave me an idea.
Sure enough if you press and hold the centre button on the Zune while listening to a podcast one of the options presented is unsubscribe. Excellent. The Gong Show for podcasts. That is exactly what I needed.
