When it comes to networks, the most powerful model is the self organizing network. That allows participants to move seamlessly between networks and takes out all the overhead of managing them.
But we really haven’t seen self organizing media networks take hold. Adsense is a self organizing network for publishers and advertisers, but not for the readers/consumers. You can’t put together a page that shows all the content that an email marketing ad has appeared on. You might be able to use search to do that, but it’s certainly not a seamless process.
This is in the context of FeedBurner Networks.
