I've occasionally listened to Richard Vobes, a UK based podcaster who produces a daily show. In his 402nd episode, he asks whether he should go commercial in order to keep investing his time in the show. Vobes says he doesn't want to do advertising in the show.
"I don't think people want adverts in podcasts. You get that on radio. Podcast is a completely different medium, and you really don't need an advert biting into your ears."
What do you think? What has your experience been with podcasting so far?
