If you're bored with blogging and ready for new worlds to conquer, podcasting might be just the impetus you need to refuel your interest in Internet publishing. The term is something of a misnomer. You don't need an iPod to create or receive a podcast, and it's not really a broadcast. What it is is hot, and with open source tools for both podcast creation and reception, it's a game that Linux users can play.
Almost anyone with Audacity, a microphone, and the proper plugins can create an MP3 audio file on any subject they wish to discuss. So what's the difference between that and podcasting? Timing and delivery. Podcasting assumes that there will be subsequent offerings, not just a one-time speech. If you use RSS the same way that news and blog sites do, your subscribers can be notified when a new offering becomes available.
Podcast receivers, then, must at a minimum be able to monitor RSS subscriptions and download new MP3 files when available. Some are just that simple. Others add a lot of functionality beyond the basics.
