I wouldn't say 'exiled': it seems more like 'distributed', but still feeding off the same pool of legal/editorial/technical expertise. What Bill Keller seems to be advocating for is a central system that tries to be objective; Greenwald's system is more like a cacophony of different prejudices that users can pick and choose individually. Theoretically, the central system is better, but in practice, it has clearly been compromised. Worse is better.

Edit: isn't there a sociological theory that basically says that an organization tends to be controlled by the people who care about the continuity of the organization, instead of the goals it represents? Like any bureaucracy, or unions. Omidyar's common pool of expertise will not have the same goals and incentives as the journalists. I'm curious how they're planning to address that issue.
