Some weeks ago I subscribed to a RSS where they publish PM pod-casts.
The firsts experiences with this kind of communication have been the next ones:
1.- The importance of the publicity as sponsor of the publisher.
2.- The communication methodology used in this channel is essential: how clear is the way the speakers talk, the pauses, tone, pitch, order…
3.- This pod-cast uses placid music that helps you to concentrate in the speaker.
4.- How similar is to the Radio.
