Authority

Zefrank:

digital natives have grown up in a landscape where access to information and influence has been flattened

Clay Shirky:

There are people horrified by this prospect, but the criticism that Wikipedia, say, is not an "authoritative source" is an attempt to end the debate by hiding the fact that authority is a social agreement, not a culturally independent fact.

Authority, historically, gets bestowed on the gatekeepers of information, such as Britannica, universities, newspapers, etc. Everything that can be digitized will be digitized, and will then be available over the internet, which is disruptive, not only to business models, but to authority.
