I have put together a simple presentation about Sina Weibo, as despite the huge run in Sina’s (NASDAQ:SINA) stock due to Weibo most non-Chinese have limited knowledge of the product itself. The document does not address censorship (See China’s Internet: The Invisible Birdcage for a longer discussion of Internet controls). We all know it is there, and Sunday we got a real time look at some of the layers of control, but this powerpoint focuses on the commercial and product aspects of Weibo.
