A radical idea to start the week -- nationalize Twitter, give the shareholders a decent exit, open it up to competition. 

Our whole political system flows thru Twitter, and the limits of Twitter have become limits of our politics. 

The company is struggling to find a business model that has nothing to do with its central role in our political life. 

Let it become the backbone, with lots of user experiences, a central station of the interactive Internet, a clearing house, and the next-level-up name service.

We need to shake things up. If we wait for the company to do it, it'll never happen.
