Facebook and Sociodigitization

Here's an interesting quotation from an LA Times article about Facebook:

Boiled down, it goes like this: Humans get their information from two places — from mainstream media or some other centralized organization such as a church, and from their network of family, friends, neighbors and colleagues. We’ve already digitized the first. Almost every news organization has a website now. What Zuckerberg [the founder] is trying to do with Facebook is digitize the second.

Question for me is--what, ultimately, are the consequences of digitizing social relations? If these social relations are secondarily, or even primarily, digitized, how does that affect the shape, content, and dispersion of the information? What is lost or gained in this process of digitalization? Finally, how do institutes of Higher Ed. respond to the shifting terrain of information dispersion, both inside and outside the classroom? Apparently, a new word has already been coined to describe this process--"sociodigitization."
