Steve Yelvington long ago identified this as the most crucial (but neglected) part of the media in a societal ecosystem: being the “Town Expert.” (The other two roles are of “Town Crier” and “Town Square” – which media orgs more or less have a handle on.)

Can’t tell you the number of proposed startups that came through the Knight News Challenge in the last two years aimed at resolving this basic issue – how can we trust what we read? Many of them are seeking to assign some kind of a numeric “reliability score” to the source of the information. Which is interesting in theory – a published climate scientist getting a 99 score, for example, while a Big Oil-funded hack gets a 12.

But in practice, systems like this would probably fall prey to the same phenomenon that plagues Digg or other sites that rely on crowdsourcing to determine importance/credibility — the efforts of a committed radical few to rig the results in their favor. Still, it would be interesting to see a major media outlet start to offer little links in superscript next to attribution, that lead back to a page describing where that quote came from, who the person is, and what their history/agenda is.
