I keep forgetting that there is a lot of confusion about podcasts and should explain:
A podcast is a prerecorded audio or video piece.
You DON”T need an ipod to listen to it or view, it can be played online or saved to your drive and will play in almost any media player.
RSS feeds now allow people to subscribe to these shows using software such as iTunes from apple, most of these aggregators are free.
I started a poker podcast site a few months ago and it is the fastest growing site I have ever built. I am in the top 5% of all podcasts for subscribers with a relatively huge audience for this medium. Some say it is my sexy Aussie accent…as mentioned in Deal magazine in a piece on poker podcasts, but I like to think there is some substance as well 
This is the perfect medium for issues such as the gambling bill and gaining the ear of people who are probably unaware of the issue.
