This is a fair point, and one glossed over in much coverage of the uprisings in the Arab world. The idea that Facebook and Twitter are key components of revolution is an easy sell, especially to a Western audience. Everybody on Facebook or Twitter feels that they, too, are part of some important dynamic that’s changing the world. To believe this in the context of the Arab world revolutions is to be as delusional as Gadhafi. Ease of communication always helps populist movements, but social media is as easily manipulated by those with a bias as state media is manipulated by dictators.
