Sina’s Weibo (microblogging) service will officially goes ‘independent’ tomorrow. The official announcement from Sina says from tomorrow (7th April 2011), Weibo service (on & will be auto redirected to and for wap user.

Launched in August 2009, Sina Weibo acquired its first 50 millions users within first 14 months and it only took another 4 months to get its second 50 millions users. And now even Tom Cruise has its account set up. Sina has spent loads of effort building the Weibo service as a platform, and adding value-added service such as check-in service, group buying service on top of it.

Insiders are telling me that Sina is even planning to get its Weibo IPO one day. If Weibo keeps growing like this in 2011, I would not surprise if it does.
