Mapping Twitter Topic Networks: From Polarized Crowds to Community Clusters | Pew Research Center's Internet & American Life Project
"Conversations on Twitter create networks with identifiable contours as people reply to and mention one another in their tweets. These conversational structures differ, depending on the subject and the people driving the conversation. Six structures are regularly observed: divided, unified, fragmented, clustered, and inward and outward hub and spoke structures. These are created as individuals choose whom to reply to or mention in their Twitter messages and the structures tell a story about the nature of the conversation."

TedX Bay Area Talk: The Myth of Selective Sharing – Digital Health Futures: Empowerment or coercion? august 2013
A fascinating talk by Marc Smith. After a while I stopped jotting down great quotes; there were too many. The bottom line is that 'selective sharing' doesn't work. Here are a few zingers: = Information that isn't public is about to be = Describing a passage in Orwell's 1984 as a "really disgruntled product review" = (spoiler alert) What if 'computer security' is an oxymoron? = Information does not "want to be free", it wants to be copied
