John's model is unique, though, not scalable and heavily gruber-dependent. It's something we can analyze as a particular phenomena, not a way to reinterpret advertising on the Web.
Look at podcasts. They are nearly all, in essence, using exactly Gruber’s model. It seems to me as though there is practically nothing else there …
(I’m not sure exactly where this podcast model is coming from. I think I first heard it – in an incarnation that is nearly totally similar to what DF does – on Dan Benjamin’s 5by5 network. That genesis would even sort of make sense, as Dan Benjamin are friends and used to be long-time co-hosts of a podcast. I obviously can’t recall exact dates, so I’m not even sure who came first there, actually. Now other podcasts and podcast networks are doing it, too.)
What that means is this: The actual hosts of the podcast read the ad in their voice, though they still say that it’s an ad read (that’s analogous to putting the ad directly on the website in the website layout together with the other content and in the RSS feed, though still marking it as sponsored content). Nearly all will also add in little personal touches. Those can be widely diverse, from a simple, slightly personalised thank you (as Gruber writes), to stories about how the hosts use the product or why they like it, all the way to specially produced editorial content for the sponsor (as Startup and Reply All from Gimlet Media are doing by, for example, interviewing their sponsors and talking to them about their business).
That’s practically identical to what Gruber does, just in another medium (and maybe the podcasts were even first and Gruber just cribbed from them and adopted it to his medium).
I honestly think this is at least somewhat workable on a wider scale. Not a billion dollar scale, sure, but a small operation making a small profit with a couple well paid staff? Sure, that’s very imaginable and partly already sort of happening.
I think Gruber is definitely unique and if he "disappeared" it would be hard to replace him.
In other words, what makes DF "work" is Gruber... and if he wasn't there... it wouldn't really work. It makes you wonder about the sustainability of "people-centric" companies.
I have thought often about this in terms of my own projects... how many of them would be sustainable without my very explicit presence?
