4. Blog by Ai Weiwei, 2006-2009

Ai Weiwei is China's most visibly dissident contemporary artist, making use of social media through his blog on the Chinese Weibo network to criticize the Chinese government in a way combative to the censorship practices of the People's Republic. Much in the way early performance artists documented with film and video, Ai used the prevalent medium of his time-the web-to examine the increasingly fine line between public life and the artist's work. Ai here used his presence to create something full and tangible rather than just a symbolic representation of his critique. In 2009, the Chinese government shut him down-he continues a very active Twitter presence.
