Off Book explores the world of modern fan culture and wonders if it's changed society: "Before the mass media, people actively engaged with culture through storytelling and expanding well-known tales. Modern fan culture connects to this historical tradition, and has become a force that challenges social norms and accepted behavior. "Fannish" behavior has become its own grassroots way of altering our society and culture, and a means of actively experiencing one's own culture."

Idea Channel asks "Is Facebook Changing Our Identity?"
"With 955,000,000 worldwide users, Facebook seems like just about everyone makes use of the social media giant to connect with friends, share photos, and update everyone they've ever met since grade school about their dinner plans. But what you may not realize is that Facebook's new timeline layout is enhancing the ability to construct our self identity by super-charging our memory."
