Good talk this morning by Leo Laporte on new media publishing, in which he talked about how podcasting has stalled out (in terms of adding users) in a way that blogs and online video haven't. He made some good points about which media work for what types of communication (video - emotional, audio - conversational, text - analytical) which make sense as general principles, albeit with plenty of exceptions.
But I wondered, as he spoke, if part of the problem with podcasting is just setting. Listening to audio at a computer is a departure from how we usually listen to talk programs, which is in the car. (In fact I do almost all my podcast listening in the car.) So I wonder if podcasters are just stuck because the opportunities for listeners to give them attention are much more limited than with video and text.
