Nussbaum blogs about the underlying importance that can be extracted from the excitement of Twitter in Iran. The younger generation used Twitter to communicate and organize mass protests against the fraudulent elections in Iran this past week.
This is particularly interesting because the government did try to contain the efforts by cutting off cellular capabilities and Twitter could not be shut down.
The interesting point that Nussbaum makes is that Twitter is not unique in this situation. Yes Gen Yers feel comfortable in a digital realm but this form of mass communication has been going on for years in the Bizarre, in the mosques and so forth.
