2005
Why 2005?
Ai was invited to start blogging by Sina Weibo, the biggest internet platform in China. He posted his first blog on 19 November. For four years, he “turned out a steady stream of scathing social commentary, criticism of government policy, thoughts on art and architecture, and autobiographical writings.”[25] The blog was shut down by Sina on 28 May 2009. Ai then turned to Twitter and wrote prolifically on the platform, claiming at least eight hours online every day. He wrote almost exclusively in Chinese using the account @aiww.[citation needed] As of 31 December 2013, Ai has declared that he would stop tweeting but the account remains active in forms of retweets and Instagram posts.
