Check out the folks listed below for examples and insight into the web 2.0 publishing revolution.

The Usual Suspects. The people I always mention, the oracles who have brought us the prophecy. Christensen, Hagel, Haque, and Kelly.

Publishing 2.0. A good blog with important news coverage, although it is still in the "property rights are important and the business model is unknown" mindset. Of course, this blog argues that intellectual property rights aren't important and that the business model is the infomediary (doing what Google does, but in a different way and at a much lower cost).
Museum of Modern Betas. MOMB is a great example of attention-oriented blogging; it's nothing more than a collection of links and blurbs on a niche topic (new web 2.0 companies). From a publishing/monetization perspective, this enables low cost production which in turn allows for healthy profit margins without requiring high profits.

Copyblogger. An example of the kind of writing that will be most successful in web 2.0; the blog offers a distinct voice (which in turn is conducive to identity building, which is becoming increasingly important; psychologically, we give more attention to well-crafted identities), and is written in a congenial style so as to enable conversation (regrettably, when you present yourself as a conspiracy theorist songwriting astrologer going around doing a country version of Eminem's "Real Slim Shady" and calling yourself Kid Mercury, you freak people out and scare them away. Such is the price for telling the truth. :) ) But hey, I know a good 2.0 writer when I see one, and that much can easily be said of Copyblogger.

Nick Wilson. The reigning king of communities, I think? At least I haven't seen anyone do it better. Like Copyblogger, an example of a very charismatic writing style which is conducive to community building, and thus is at the heart of writing/blogging in web 2.0.
