Robert Downey Jr is on "Weibo" but not on Twitter

Profile Picture of Robert Downey Jr on Weibo

This is pretty odd, but also a little bit funny. The Iron Man actor, Robert Downey Jr. is not on Twitter, has never been on Twitter, and will most likely never be on Twitter. There have been many parodies and impersonating Twitter accounts pretending to be him, yet still, he has chosen not to spend five minutes to sign up creating a verified profile so far.

I am amazed that he is on Weibo instead 
Weibo is a Chinese microblogging website, and is very similar to Twitter. Weibo is one of the most popular websites in the country China -- About 3/10 of all Chinese people uses Weibo, meaning, almost 400 million registered users since the middle of 2012. Twitter has been up since 2006 - but has only 100 million more registered users than Weibo, yet only 200 million users are active.

Robert D Jr, updated his Weibo with this:

People who know me back in America know that I’m very interested in all things Chinese. - 在美国了解我的人都知道我对与中国有关的一切事物都很感兴趣。

Very funny in my opinion that he is using Weibo, but not Twitter. Here is his Weibo account http://www.weibo.com/RobertDowneyJrCN
