Just as many of us like to read things of interest, so do many like to listen, which is where podcastings can be a boon.
I must admit I've alway liked listening to the radio, sometimes preferring it over television, so the ability to podcast, with its record now and play later ability, makes it appealing. I can see many others appreciating it as I do.
But my initail try out of podcasting was not totally succesful. Some sites on the internet were easy to find podcasts, but when I tried finding some very specific things of interest, then it became more difficult. I found some interesting websites, but finding the podcast within them wasn't always easy. No doubt though, experience will improve my ability to find these.
