Want to find out what programs are available for listening and subscribing to podcasts? How about creating your own? Or maybe you just want a simple definition, because so far no one has been able to give you a straight answer as to what the hell a podcast is (and what it isn't).
Well, the Unix and Linux Podcasting Guide from RootPrompt is pretty much the end-all, be-all of podcasting resources. Check it out if you use Mac OS X, Linux, or Unix. There's good general information there for Windows users as well, but you'll have to download utilities elsewhere.
