And that begat the political blogosphere, which nailed Trent Lott, to start with -- and science bloggers, and Brooklyn bloggers, and Facebook, Twitter etc etc. 
The point is -- yes we still have gatekeepers. We still have TV and sleds, but we also have cable and snowboards. All layers stick around. But we have something new now, something we didn't have before. 
Yesterday's gatekeepers worked for Microsoft and Sun and today's gatekeepers work for Google, Facebook and Apple. And they have always worked for the VCs. Gatekeepers love money, they swarm around it, and believe all kinds of myths about it, such as it has something to do with innovation. 
The users write about what they love, and that feeds the people who create with love, and new stuff is born, and yes we get new gatekeepers, but the seeds of their route-around are already planted. 
So much more to say. But that will have to wait for another event.
