Baidu Baike
Although the Chinese write fewer emails, they enjoy other online communication tools. Users form their communities based on different interests. Bulletin boards on portals or elsewhere, chat rooms, instant messaging groups, blogs and microblogs are very active, while photo-sharing and social networking sites are growing rapidly. Some Wikis such as the Sogou Baike and Baidu Baike are "flourishing". Until 2008 the Chinese Wikipedia could not be accessed from mainland China. Since 2008, the government only blocks certain pages on Wikipedia which they deem to contain controversial content.
