Twitter launches attack on China, Iran

Chief executive and co-founder of Twitter Evan Williams has joined Google in whingeing about China.

He said he has people working on "interesting hacks" designed to stop foreign governments blocking its content.

Williams, speaking at the World Economic Forum, said he admired Google's attempt to rail against China where, he said, Twitter is "partially blocked".

"The most productive way to fight that is not by trying to engage China and other governments whose very being is against what we are about. I am hopeful there are technological ways around these barriers," he said.

He claimed to have people working on technology to stop governments - other than his own - blocking content on the site.

Twitter made much capital out of having a couple of Iranians tweeting, as if it made a difference.
