During the September 11 riots outside the U.S. embassy in Cairo, a staffer's sarcastic response to a tweet from the Muslim Brotherhood led to an exchange that was widely covered by the mainstream media. The tweets came on the heels of a controversial statement that the embassy published on its website shortly after an Egyptian salafi television show broadcast The Innocence of the Muslims, a crude U.S.-produced YouTube video that portrayed the prophet Mohamed as a womanizer and charlatan.

“This is a key point for digital diplomacy – the importance of reaching a broader audience, not just the same old people who usually follow foreign affairs.” As such, top diplomats are increasingly holding live, virtual chats on social networks to engage with people whom they would otherwise never meet.

The use of Twitter as a diplomatic tool fits in nicely with the new sense of political empowerment that has accompanied the rise of social media. As Internet connectivity rates continue to grow (particularly through the rapidly expanding availability of smartphones), Twitter helps foster an unprecedented sense of community among members of the global public.

MINUTES after last week’s violent attacks on America’s missions in the Middle East, the country’s embassy in Cairo was already on Twitter. It tweeted an emergency number for American citizens. It criticised Egypt’s Muslim Brotherhood for supporting the protests on their Arabic feed. And it thanked fellow tweeters for their condolences on the murder of the American ambassador to Libya, Christopher Stevens.
