Thinking about podcasting.

I'm thinking about podcasting -- both in the sense of wondering about it and in the sense of kind of planning to do it. So I'm trying to get a sense of what works. I've browsed around in the iTunes "audio blogs" category. But really, I haven't run across anything that's the slightest bit appealing.

I'm sure many of the regular radio shows being podcast would be worth listening to, just as radio is worth listening to. But I want to hear something that has some real blogginess going for it. Any ideas?
