China’s online community brimmed with disappointment - if not despair - on Tuesday after online media reported that Iran had granted its citizens access to Facebook and Twitter. Both sites had been walled off from Iranian users since 2009. This leaves China, along with its neighbour North Korea, among the very few countries which still block Facebook and Twitter. “Iranians are now returning to Facebook, yet we Chinese haven't even met Facebook,” one microblogger commented on Weibo.

Almost every major political figure has a social-media presence today. Chechen strongman Ramzan Kadyrov is an Instagram addict, as is Syria’s first family. Hugo Chavez was a prolific tweeter, and Fidel Castro blogs occasionally. Iowa senator Chuck Grassley live-tweets University of Northern Iowa Panthers women’s volleyball matches. Yet nobody’s quite as strange as Iran’s Supreme Tweeter, Ayatollah Ali Khamenei.

Twitter, Facebook, and other social networks are back online in Iran. It’s been four years since the government shut off access to most social media during protests following the 2009 presidential elections. But a new administration, elected in June, has vowed to improve communications in Iran and liberalize access to the internet. President Hassan Rouhani is himself on Twitter.

In recent days, the blogosphere and the international press have been abuzz over the public relations campaign undertaken by Iran's new president, Hassan Rouhani, and his foreign minister, Mohammad Javad Zarif. Tweets by accounts associated with both men — caveat: the president has not explicitly confirmed his —can be credited with nudging Iran’s public posture on Syria in a more moderate direction, and distancing the new Rouhani administration from the anti-Semitic trope of his predecessor, Mahmoud Ahmadinejad.

Norwegian Internet browser maker Opera Software expects its data-light mobile phone browser will play a central role in a Facebook-led project aimed at bringing Internet access to third-world consumers, Opera's CEO told Reuters. The project, called Internet.org, was launched last week by Facebook Chief Executive Mark Zuckerberg, who says he wants to make Internet access affordable for the 5 billion people around the world who are not online.

Mohammad Javad Zarif, Iran’s new Minister of Foreign Affairs,posted a short piece with six questions about Syria on his Facebook page. 1,100 comments left on the Minister's post until Saturday,30th of August. Some called Zarif on the hypocrisy of criticizing Western intervention as intervention, when Iran has its own presence on the ground.

A Facebook post said to be written by the 11-year-old son of the Syrian president, Bashar al-Assad, and “liked” or commented on by several people who appear to be the children and grandchildren of other senior members of Mr. Assad’s government, may offer a glimpse into the mindset of Syria’s ruling elite as the country braces for a potential Western strike in response to a chemical weapons attack on Aug. 21.

A Spanish mayor has sparked outrage by using his Facebook page to publish a picture of Gibraltar – as it would look if the Spanish army invaded. The image shows a Spanish flag flying high on the Rock, the silhouette of a bull on the lower slopes and triumphant marching Spanish troops in the foreground. The mock-up appeared on the page of Francisco Javier Pérez Trigueros, a nationalist whose previous posts include details on the history of the Spanish flag.
