As the embattled government of President Mahmoud Ahmadinejad appears to be trying to limit Internet access and communications in Iran, new kinds of social media are challenging those traditional levers of state media control and allowing Iranians to find novel ways around the restrictions.

Iranians are blogging, posting to Facebook and, most visibly, coordinating their protests on Twitter, the messaging service. Their activity has increased, not decreased, since the presidential elections on Friday and ensuing attempts by the government to restrict or censor their online communications.

On Twitter, reports and links to photos from a peaceful mass march through Tehran on Monday, along with accounts of street fighting and casualties around the country, have become the most popular topic on the service worldwide, according to Twitter’s published statistics.

A couple of Twitter feeds have become virtual media offices for the supporters of the leading opposition candidate, Mir Hussein Moussavi. One feed, mousavi1388, (1388 is the year in the Persian calendar) is filled with news of protests and exhortations to keep up the fight, in Persian and English. It has more than 7,000 followers.

Mr. Moussavi’s fan group on Facebook has swelled to over 50,000 members, a significant increase since election day.
