A list of podcasts, need I say more? If the list grows enough, it may just get split into categories. :D
What is a podcast?
A podcast is a radio like production that many people produce on the internet. The file will normally come as a mp3 or other well known media file, so owning an iPod is not necessary. The idea of the podcast is to put the audio on a mp3 player (or other portable media device) to play back while travelling although many people will simply listen to it on their computers.
