Interesting, I wonder how much of this is an artifact of podcasts oriented more towards a hobbyist audience vs. a professional audience?
Podcasts aren't expensive to produce at a basic level, it's mostly just the hosts sitting around and chatting on skype for an hour every week or two. I'm only aware of one podcast I listen to that frequently asks for contributions, and that's mostly because the hosts have found they work best when they're physically co-present and have to fly one of the hosts out every month to record a bunch of shows all at once.
> I'm not too bothered with these, as compared with the type of adverts you'd find on commercial television or radio
Yeah, I agree. When the parent discussed adverts before I was thinking of the more commercial radio type. I think it's an effort to try to monetize podcast audiences, but at least for me I'm able to find more content than I can listen to, run by hosts that aren't all that interested in turning their hobby into a money making venture.
