Andrew Peterson said something interesting in his interview over at Between Two Worlds:
I think Facebook is our culture's answer to the disappearance of the close-knit, small town community. Finding out on Facebook that so-and-so has a cold, or stubbed their toe, or is reading a certain book is the 21st Century equivalent of strolling the town square or having pancakes in the diner. It's small talk. And small talk is okay. You wouldn’t necessarily call your friend to find out if his toe got stubbed; it's just nice to know. The thing is, even small towns have secrets. I know because I grew up in one. There were murders. Suicides. There was bigotry and alcoholism and despair. Beneath the surface is the same darkness you see on the news in big cities and war-torn countries. Small talk doesn't address that secret loneliness. Neither does marriage, for that matter. Only Christ can. Only he has the power to step in and throw back the curtains.
I never would have thought of it that way, but maybe he's on to something.
