Business: Podcasting: The radio-free radio experience

Not that there is any single 'podcasting realm' - which is one of the aspects podcasters find so appealing. There is no Federal Podcast Commission, no corporate radio giant dictating topics and playlists. Content can be as niche as niche gets; some topics listed on Podcast Alley - the Billboard of podcasts - include quilting, 'gay sexcapades,' and Florida Gulf Coast University hockey.
