Technology Review reported a comparison of Twitter with its Chinese counterpart, Sina Weibo. Twitter has been banned in China since 2009 and Sina Weibo was introduced a month after its prohibition as its replacement. The conclusions of the comparison were a far greater number of retweetings on Sina Weibo. The behaviour between the two systems were similar but Sina's results were skewed by the lack of realtime news.
Yes, the Chinese do not comment on news. There won't be any news from Satellite 2 for Shanghai in the near future.
