For a few hours it seemed as though progress was being made in penetrating the wall of censorship that the Chinese authorities had built around the country’s Internet services. Yet barely 24 hours after it was registered, The New York Times’ Sina Weibo account was suspended, before being mysteriously reinstated early this afternoon. The Times had joined Weibo, the Chinese Twitter-equivalent, at the same time as it launched its Chinese language site, http://cn.nytimes.com, and within a few hours the NYT account had been "liked" by 3,300 people.
