Twitter has been a bit of a thorn in the side of the Iranian government, giving the world a seldom seen view of the political unrest in the country, especially during the 2009-2010 election protests, the so-called Green Revolution.

Social media is still banned in Iran, which made the Twitter exchange between Twitter founder Jack Dorsey and newly elected President Hassan Rouhani so newsworthy.

Dorsey first tweeted, “Good evening, President. Are citizens of Iran able to read your tweets?” And, in response, Rouhani said, “Evening, @Jack. As I told @camanpour, my efforts geared 2 ensure my ppl’ll comfortably b able 2 access all info globally as is their #right.”

Social media still banned. Will this exchange signify coming change? To me, this is a perfect litmus test. Turn on the social media for the people, or it’s just words.
