Podcasting is probably the closest thing right now to the authenticity, diversity, and creativity of the early web. There's a massive diversity of podcasts out there on every subject and even many of the purely amateur ones are of very high quality.
I agree wholeheartedly! With my podcasts I feel I know the hosts, I look forward to the content, they may have ads but they pick them to match the content and they are still honest about the products they present in those ads. I don't know what it is, but it feels much more personal (I mainly listen to Jupiter Broadcasting podcasts (no more ads since recently) and some related ones but also Twit and NoAgenda (no ads at all) from time to time. Looking very much forward to the continuation of Stephen Fry's Great Leap Years...
I even feel personal interest in the lives of the hosts. Some I've been listening to for over a decade.
