Before you get too deep into podcasting, you should have some kind of idea about what you will be discussing.

There are lots of topics.

• You can explain how to do something.

• Many of the first podcasts have been about personal interests like music, art, hacking and culture.

• As corporations and politicians get involved, their topics are helping to support the corporate or business line.

• News organizations are using podcasting to provide an alternate transmission channel for their content.
