“PODcasting will shift much of our time away from an old medium where we wait for what we might want to hear to a new medium where we choose what we want to hear, when we want to hear it, and how we want to give everybody else the option to listen to it as well.” - Doc Searls
Nice overview of the "next big thing", podcasting. Think of it as TiVo for the multimedia web. Any site that publishes audio or video and has an RSS (XML) syndication feed that supports enclosures can set it up so that you can download multimedia in the background, and then play it at your convenience on your computer or after transferring it to a portable device, like an IPod.
The technology behind this is DIY; no advanced computer degree required. If you know the basics of a syndication feed, you can do this. And if it catches on, you can expect that most weblogging software will incorporate the ability to generate enclosure tags into the feeds they already publish. Currently available, mainly tech-talk from geeks; don't be surprised to see traditional content creators get on the band wagon soon though.
