Initial side question: How is podcasting different than simple audio files?

Quick and smart definition:

• Wikipedia definition

• Here is the audio description of the definition

• "a collection of digital media files which is distributed over the Internet, often using syndication feeds, for playback on portable media players and personal computers."

• "distinguished from other digital media formats by its ability to be syndicated, subscribed to, and downloaded automatically when new content is added, using an aggregator or feed reader capable of reading feed formats such as RSS or Atom."

• MOBILITY, SUBSCRIPTION & AUTOMATIC DOWNLOAD

Some examples of podcasts and ways to subscribe

• iTunes for example has many podcasts that one can sign-up to.

• So you can actually from your iTunes interface, search for podcasts in the same way that your search for music.

• Podcasts are searchable over the net as well:

• Searching for podcasts through Mediafly

• Searching for podcasts through Podcast.net

• EPN - Educational Podcast Network

• Many ways to produce podcasts

• Recording with a desktop app and then uploading the MP3 file

• Using Gabcast to record podcasts
