Social media in times of political crisis: six "lessons learned"

In the New York Times, this thoughtful piece by Noam Cohen on the links between online communication tools and political crises -- namely, the ongoing turmoil in Iran:
# Tweets Are Generally Banal, but Watch Out

"The qualities that make Twitter seem inane and half-baked are what makes it so powerful," says Jonathan Zittrain, a Harvard law professor who is an expert on the Internet. That is, tweets by their nature seem trivial, with little that is original or menacing. Even Twitter accounts seen as promoting the protest movement in Iran are largely a series of links to photographs hosted on other sites or brief updates on strategy. Each update may not be important. Collectively, however, the tweets can create a personality or environment that reflects the emotions of the moment and helps drive opinion.

# Buyer Beware

Nothing on Twitter has been verified. While users can learn from experience to trust a certain Twitter account, it is still a matter of trust. And just as Twitter has helped get out first-hand reports from Tehran, it has also spread inaccurate information, perhaps even disinformation. An article published by the Web site True/Slant highlighted some of the biggest errors on Twitter that were quickly repeated and amplified by bloggers: that three million protested in Tehran last weekend (more like a few hundred thousand); that the opposition candidate Mir Hussein Moussavi was under house arrest (he was being watched); that the president of the election monitoring committee declared the election invalid last Saturday (not so).
