Social networking will always be a double-edged sword. The danger of everything from Internet bullying to predation is an inescapable facet of 21st century cyber culture, something parents must deal with as they discern guidelines for their children's access to social networking sites.
In addition to those dangers, there are plenty of other risks inherent to social networking, especially for teenagers: the drain on attention spans, the potential to aggravate compulsive behavioral disorders and to aggravate the already intense proclivity to adolescent solipsism. I particularly worry about how social networking contributes to the generalized loss of capacity among teens and "emerging adults" (persons between the ages of 19-29) to engage in normal conversation: I mean, like, their ability to, like, sustain attention on a single matter for long periods of time, you know, for like more than three minutes.
Then consider this. The New Oxford American Dictionary word of the year for 2009 was 'unfriend'. To 'unfriend' someone is to remove them as a friend from a social networking site (such as Facebook). As benign and even amusing as this cultural factoid may seem, it sheds a great deal of light on the potential downside of social networking and the negative impact it can have the culture.
First, I fear it bespeaks the degree to which friendship has been emptied of substance, even as we place such a high premium on friendship these days that we coax ourselves into thinking we can form "friendships" with the click of a mouse. We obsess over being friends with as many people as possible only at the risk paradoxically of emptying friendship of its significance, cheapening it, and trivializing it.
And while the verb 'to friend' is something of a less commonly used neologism (evoking the older English form 'befriend'), 'to unfriend' -- a negative verb form -- is by far more common. That simple fact should give us much pause.
How does the possibility of "unfriending" a Facebook acquaintance impact our conception of human relationships -- even subconsciously? We have already been a quick-fix-pop-a-pill-make-the-difficulty-go-away culture for decades. Unfriending someone is the quickest fix yet. Mad at a Facebook friend? Click. Unpleased by a comment on your wall? Click. He's now your ex? Click. She wouldn't dance with you? Click. Unfriending, in the psychology of many, provides a scintillating new outlet for our most knee jerk, individualistic and selfish reactions to the basic challenges of being social animals by nature.
