CIC published a new version of "Social Media Landscape @China".
Its 2012 version added "Pinterest" as a object. And looking this landscape, services of similar with Pinterest already started in China(ex. Huaban, Duitang, etc).
And there is only Chinese version, but a history of this landscape is also available.
It's a useful tool for leaning the history of social media in China, isn't it? :)
