What is it? Is it difficult to set up, I have a friend who request for a podcast in his website, but i never touch it before or learned about it..will really appreciate for the assistance..and this question might sound to noobish and useless for some, apologise for that.. thanks.
In a nutshell - Podcast is identical to RSS feed. The only difference is that podcast items link to media files instead of web pages. All you need is a microphone. Record your audio, convert into MP3, upload, then put together your XML file - and you have your podcast.
