[All About] Podcasting
"At it's core, Podcasting is audio blogging. The is the regular publishing of information, but in audio format instead text. Because of the rich nature of audio information, podcasts can take on additional dimensions of communication, such as sound effects and music, these additions facilitating more effective communication.
