Sure, I should maybe post this link over at WRR, but if you are there, you already know what a podcast is.
If you aren’t listening to podcasts now but are curious about them, this would be a great place to start. It tells you what a podcast is, what you do with them and how to find them.
From the site.
The technology of podcasting allows you to publish rich media (audio or video) that people can consume on the web and subscribe to in order to get automatic updates. Think of podcasting as a digital video recorder for the web. As a podcaster you make content available that people can get how they want, when they want. All anyone really needs to consume podcasts are a computer and an internet (preferably high speed) connection.
Worth checking out even if you are already podcast savvy. And, if you are, pass the link along to someone who you think would benefit.
