What is "podcasting"?Podcasting is a new way to create and listen to radio. Sorta.
According to Wikipedia, ”Podcasting is a way of publishing files to a website that allows users to subscribe to the site and receive new files as they are posted. Most podcasts are spoken word audio created by individuals, often on a particular theme such as technology or movies. Because new files are downloaded automatically by subscribers, podcasting allows individuals to have a self-published, syndicated radio show.”
Another way to look at it is what would happen if you combined a TiVo, with your MP3 player, with the web—so, you could listen to a selection of content as varied as the web, whenever, and wherever you want.
iPodder : iPodder is technically a "Media Aggregator," a program that allows you to select and download audio files from anywhere on the Internet to your desktop.iPodder makes the process easy by helping you select audio files from among the thousands of audio sources on the web and downloading those files to your computer. Once you select a feed or location, it will download those files automatically at times you specify and have the files waiting for you on your computer, so you don't have to spend a lot of time manually selecting and waiting for downloads. You can play your selected audio files using iTunes or other "jukebox" software, or load them on to your iPod or other portable digital media player to play anytime you want.
iPodder is open source and cross-platform compatible, which means it doesn't matter if you have a Mac, Windows, or Linux computer. It just works.
Odeo : What does Odeo do?Odeo makes all of the above easy, so you don’t have to know how it works. More specifically, Odeo consists of three major parts: A catalog of audio content, of all types, which is constantly being added to. The Odeo Syncr, which let’s you download anything in the catalog (and, optionally, put it on your MP3 player). And creation tools, including the Odeo Studio, which let you publish your own audio content, which will then show up in the catalog. (The creation tools aren’t ready for public use yet, though.)
Odeo is all web-based.
