We published an introduction to podcasts a little while ago and discussed a number of aspects of podcasts and podcasting. PBS has a great introduction of their own which really goes into quite a bit of helpful detail. It is titled "Your Guide to Podcasts" and is yet another fantastic post for those who are still a little unsure about podcasts. The one unfortunate thing about podcasts is the name "podcast" because it suggests that you have to have an iPod to listen to podcasts. This is not necessarily the case. Even though some podcasts are formatted for use in iTunes and on an iPod, most of them are available in mp3 format which can be played on pretty much any digitial audio player.
