Sociability Fatigue

A recent snippet in the Denver Post entitled "Feeling an overload of social networking" highlighted what it called "online sociability fatigue".  At the coffee shop I frequent, a regular conversation partner commented on the fear young people have of being left out or becoming irrelevant.  I wondered if this fatigue might compel us to anchor our significance in something greater than the mediated interfaces that want to define us.  Then all the  social networking technology would become something that enhances our day (and us) rather then defines it (or us).
