Podcasting is the stupidest word the "blogosphere" ever coined.
A Podcast is a fucking MP3 file. Last time I checked, we called these MP3 files. We've been doing so since 1994.
Hey, what happens when you use another music player to play an MP3 file? It fucking plays! If I had a mystical audio file that was called a Podcast, it would only be playable on a fucking iPod.
Digital audio recordings of interviews and events were around years before the iPod was even blueprinted.
