Not being an ipod user yet, I found this paragraph explained it well.
Break PODCAST down into two parts. First the POD: you can either listen to a podcast on your computer or transfer it to your portable audio/video device, which means that file is Portable, and it’s On-Demand because you can listen to or watch it when you want, where you want. The CAST means the file is sent out to you over the Internet, in the way a “broadcast” comes to you over the radio or TV airwaves. But instead of using a radio or TV, with podcasts you use a computer connected to the Internet, and on that computer you have a program that allows you to subscribe to, manage, and listen to or watch your favorite podcasts.
I looked at podcast.com and it has 60,000 audio and videos for people to download and you can choose from various categories. I'm starting to think that people will never move from their home as they can now get everything via their PC. Will people stil want to meet face to face in the future? I suppose if you find people with common interests who are still geographically close you will meet up (Social networking where you invite people to join your site). Still trying to add some podcast feeds but my PC at home may need some upgrades to accept the new info.
