Ok, everyone is agog at the news that Scoble is joining Podtech.net. Well, I've just spent awhile wandering their site, and I have a simple question: What's the business model behind this? Never mind the content of the podcasts - they could all be really, really engaging - I'd still have the same question. I don't have to pay to listen (and I'm not sure I would - there are too many good free casts available). I don't get ads, so they aren't using a sponsor model (at least not yet).

I've had the same question about RocketBoom, actually. I like their stuff, but I have no idea how they can make money off the segments they do. It's all really nifty stuf, but where's the payoff?
