I have never listened to and participated in any podcasts. At first, I thought it's nothing more than normal broadcasting except we can store podcasting files onto our computers. But then I found out there is a new technology that can automatically filter out all the umms and uhhs and coughing and sniffing and slurping noises from our podcasts. I don't know why, but they call this "writing"!?
Podcasting is going to make digital storage of lecture and meeting information much more useful and achievable. One thing I am worried about is whether it will make inappropriate contents more accessible to children.
