Baidu launches microblog: Say it

Baidu's post bar has been so successful that its microblog is called "Say it" http://t.baidu.com/. It is currently in private beta and only invited users can register. Even with the invitation, registration also needs "180X180 pixels above the real person avatar, ID number, mobile phone number and real name", some people found that registered users can not fill in the ID number, Baidu ID database can do name association, it seems to have close cooperation with the Ministry of Public Security.
