I've been trying to come up with a concise way of saying this, the Web 2.0 model served its purpose, it got content management into every nook and cranny of Internet life. But at a cost.

We gave up control over the experience to companies whose incentives and interests conflict with ours. A necessary bargain when running a server is so complex and expensive.

But all that has changed with the ability to access cloud storage from apps written in JavaScript that run in the browser. Software that used to require a central server, and was easy to attack, and had to scale for all sizes of use-cases, now can run in the browser, with little if any loss of power.

New models for communication can develop, independent of the limits and needs of companies that run the Web 2.0 servers. I don't think Web 2.0 will go away, but a new net can take its place beside it. And that's all that's needed to boot up a new layer.
