"Everywhere you turn online these days you hear the word "podcast" or "podcasting." No, it's not some broadcasting method used by Martians, even though it might sound like it. A Podcast is just an audio file that is syndicated via an RSS feed, that you download and listen to with your computer or a portable device such as an iPod. What makes it different from an ordinary RSS feed is the audio component included in the "enclosure field." Think of it as a feed that talks to you."
