I haven’t met a single person who uses social media heavily who isn’t struggling to define what the constant, low-level publicness does to him or her. Even those who are supremely comfortable with the medium ponder if they need to get away from Twitter and Facebook now and again. No one is quite sure what it does to them to have ‘friends’ instead of friends or to 'like’ things instead of liking things. Maybe nothing, maybe a lot. So, I looked on with interest when University of Maryland graduate student Nathan Jurgenson tweeted about a frame that got his students talking. I like it because it’s not an all or nothing question. It’s only about what social media amplifies and restrains. Jurgenson asked his students to consider whether using Facebook emphasized the 'me’ or the 'I,’ a distinction made by social thinker George Herbert Mead.
