I’m not even sure these new instruments are genuinely “social.” There is something decidedly faux about the camaraderie of Facebook, something illusory about the connectedness of Twitter. Eavesdrop on a conversation as it surges through the digital crowd, and more often than not it is reductive and redundant. Following an argument among the Twits is like listening to preschoolers quarreling: You did! Did not! Did too! Did not!
The shortcomings of social media would not bother me awfully if I did not suspect that Facebook friendship and Twitter chatter are displacing real rapport and real conversation, just as Gutenberg’s device displaced remembering. The things we may be unlearning, tweet by tweet — complexity, acuity, patience, wisdom, intimacy — are things that matter.
