Podcast Realization

I just watched the videos that explain what podcasts are and how they differ from normal audio and video files. After surfing the web and taking a look at different podcasts, I can see how useful and fun they can be. It is like taping your favorite TV show via your computer except it doesn't have to be a "TV show". It can be anything from an instructional video to an audio interview with a band. The best part is that your computer downloads it for you when you are not around- how cool is that ??? I always assumed that I knew what a Podcast was but now I actually do know and it is pretty radical.
