Do as I say, don't tweet as I do.
That seems to be the message from Iran, where the short-messaging social network is apparently permitted for the leadership but officially banned for the average citizen.
One tweet – from President Hassan Rohani, who was attending the United Nations General Assembly meeting in New York – prompted a snarky response from Twitter's chief, Dick Costolo, Time magazine reported.
Costolo took advantage of a tweet by Rohani, which addressed Iran's negotiations with the West over the country's nuclear program, to call the president out on the double standard.
Here's the exchange:
.@HassanRouhani Mr. President, enjoying your Tweets from the UN. We would love the Iranian people to enjoy them as well. When will that be?
The Iranian president's Twitter page shows him to be a regular user of the social network.
Rohani has publicly taken positions on media more liberal than those of his predecessor, Mahmoud Ahmedinejad.
And earlier this month Rohani called on the country's senior clerics to accept the Internet as an instrument of education.
