TalkShoe looks like it might be useful for people who aren't as technically savvy but still want to do podcasts, as all you need is a computer, a phone and their software. There are clients for both Mac and PC, which you can download after signing-up. I'm intrigued by the interactive element - so it's not a traditional "I talk, you listen" podcast as much as it's a hosted discussion.
Tip of the hat to Eric Rice for making me aware of TalkShoe.
Plenty of previous discussion on this blog about podcasting.
