Jack Dorsey, Twitter's chairman, started the exchange with Iranian President Hasan Rouhani, who has used the medium to reach out to the international community despite the fact it's officially banned in his country, The Daily Telegraph reported Wednesday.
"Good evening, President. Are citizens of Iran able to read your tweets?" Dorsey asked.
Rouhani replied he's working to make sure Iranians would "comfortably b able 2 access all info globally as is their #right."
Twitter and Facebook were banned in 2009 by Rouhani's predecessor, Mahmoud Ahmadinejad, when opponents used the Internet to organize mass protests over his re-election. Rouhani, considered by many to be a moderate, campaigned on easing Iran's Internet censorship.
