Simply put: There was no Twitter Revolution inside Iran. As Mehdi Yahyanejad, the manager of "Balatarin," one of the Internet's most popular Farsi-language websites, told the Washington Post last June, Twitter's impact inside Iran is nil. "Here [in the United States], there is lots of buzz," he said. "But once you look, you see most of it are Americans tweeting among themselves."
As the author sees it, although Twitter played a big role in spreading word about events in Iran around the world, "good old-fashioned word of mouth was by far the most influential medium used to shape the postelection opposition activity." So to over emphasize the importance of Twitter is a rather terrible slight to "the Iranians who have made real, not remote or virtual, sacrifices in pursuit of justice."
For whatever it's worth we seemed to have been on both the breathless and skeptical sides of the revolution issue.
