In the next three months, users of China's microblog weibo.com --- "weibo" is the generic Chinese term for Twitter-like platforms --- run by the huge sina.com (the English site is here) news portal, entertainment and blogging site, will have to start providing their real-world identities to the site, instead of simply being able to register. It seems likely the users of competitor tencent.com (English here) will have to do the same, though the government hasn't made that clear in recent announcements, dating back to December 16.

In the latest sign of increasing pressure on Chinese companies to tighten control of the Internet, Chinese authorities convened an unusual seminar in Beijing for senior executives of 39 major enterprises involved in Internet services, technology and telecommunications.
