Namecoin and the system Assange is suggesting is unnecessary and highly complex, if it could be achieved and adopted to any meaningful level at all.

The obvious hammer for this nail is just a radically transparent information system with accountability for public information an individual contributes to the public record.

Search algorithms are, largely, a commodity code now. Before you argue otherwise, the complexity and proprietary nature only arises when you try to show preference to less desirable content before other content information consumers desire. Ie - advertising

Even with advertising in the mix, it is trivial for a search company to append a query score with its query results. With a transparent query score and a transparent algorithm, the community has a trustworthy third-party between the content producer and consumer.

Transparency and that includes the information source!!!
