"Twitter on the Barricades: Six Lessons Learned" is an even-handed analysis on the effects of Twitter on the Iranian demonstrations—and a peek into the future of its liabilities & assets for future movements and the media that covers them.
In The New York Times, Noam Cohen writes:
“But does the label Twitter Revolution, which has been slapped on the two most recent events, oversell the technology? Skeptics note that only a small number of people used Twitter to organize protests in Iran and that other means — individual text messaging, old-fashioned word of mouth and Farsi-language Web sites — were more influential. But Twitter did prove to be a crucial tool in the cat-and-mouse game between the opposition and the government over enlisting world opinion.”
It is interesting that is (somewhat) concludes that Twitter continues to be oversold in the West.
