Podcasting
I just realized that everyone may not know about podcasting - or the art of taking an audio stream/file and wrapping it in an RSS feed. This allows the listener to add this to their iPod as part of syncing with iTunes (hence the name). If you don't have an iPod - don't worry. The RSS feeds are standard MP3 files and can be move to any device that can play the file format. Visit www.ipodder.org for more information and links to software and podcast feeds.
Enjoy!
