Podcast = express yourself, or let us...
We still have many people unsure as to what a podcast is. Podcasts are a way of creating your own channel that people can subscribe to and watch on their computers, TV's, phones and more.
They are like a radio or TV show posted to the internet. When a user subscribes to the show (usually via iTunes) it will regularly check and automatically download when a new show has been posted.
They are also known as net-casts, and are changing the way of media distribution.
Not so long ago, the dream of having a TV or a radio show was way out of reach for close to all. With the development of the internet, personal computers and AV equipment it is all at our doorstep.
