Some have already dubbed the protests in Iran to be the "Twitter Revolution."
Certainly the political unrest in Iran has demonstrated as never before the power and influence of social media.
How big has the subject been in the social media conversation in recent days and what role does the discussion appear to be playing?
The Pew Research Center's Project for Excellence in Journalism took a special look this week at the role of Twitter and other social media to find out in an expanded version of the weekly New Media Index.
From blogs to "tweets" to personal Web pages, the topic dominated the online conversation far more than in the mainstream media as users passed along news, supported the protestors and shared ideas on how to use communication technology most effectively.
In addition to the blogs and social media regularly monitored, PEJ for the week of June 15-19 examined the links being posted (or tweeted) according to the tracking site Tweetmeme. In much the same way that Icerocket and Technorati track links from blogs and other types of social media, Tweetmeme tracks the "hottest" links on Twitter.
