What is Podcasting?

"Podcasting is delivering audio content to iPods and other portable media players on demand, so that it can be listened to at the user's convenience." http://www.podcastingnews.com/articles/What_is_Podcasting.html
However after listening to the introductory podcast on iTunes I found that there is much more to podcasting. Anyone can create a podcast and call it that, a podcast. However one thing that I got out of listening to the Podcasting for Dummies podcast was that a podcast has to be about some sort of content. You cannot just ramble on about your daily life and call that a podcast. That would be considered an audio blog, because it does not have a set topic.
Another important part of podcasts is that they are not a one time thing.  You cannot make one podcast about a subject and be done with it. They must be part of a series. Much like a new tv show, their must be new ones for the listeners to tune into.
I personally do not like podcasts. I find that if I do not have something to watch I tend to lose focus easily. I have never liked talk radio. I find I cannot focus on what is being said. I hate sports radio the most, where they try to play a sporting event over the radio. Who cares about that awesome catch if I cannot see it? I do not know if there are others out there who feel the same way as I do. What about you fellow classmates? Do you like podcasts?
