With great power comes great...tweets?

Many of you have probably already seen this video about the Everest-esque enormitude (I made up that word) of social networking. I, on the other hand, still spend my time in ways like picking out stamps, so I missed out on when this went viral. But it found me nonetheless, and now all shapes and sizes of questions are surfing my brainwaves. Would we be better off without all this? How is this affecting our day-to-day relationships? Individuality? How much is too much? Is this revolution GOOD?
