The whole argument in the piece is invalid. People are using Twitter and Facebook to reduce the amount of time they spend with people whilst trying to stay in contact with people. My girlfriend uses it and I want to block the damn thing because she'll spend an hour on that 'keeping in touch' instead of us going out for a meal with the people we're trying to keep in touch with.
People went from keeping blogs to using twitter and now instead of making a post or two they'll make a couple of microposts. It's completely, inherently moronic. I contend that people using these completely unneeded services are far dumber than the people clicking google ads.
I have little doubt there are people who've spent months worth of time on Facebook when they could have used that time to actually be with family and friends. Or shit, they could have worked the time they wasted and went on a nice vacation to Paris.
This is amazingly condescending... It completely misses the point of figuring out what people want and assumes everyone is doing nothing better with their time.
For example: I understand twitter just fine and couldn't care much less about it.
