China's Facebook Syndrome

(Corrects the year Google diverted its Chinese-language search traffic to Hong Kong in paragraph 6.)

Since 2009, China has blocked Facebook, the world's largest online social media network. This year, Renren, one of China's largest social networks, plans to raise $500 million on the New York Stock Exchange (NYX). So a Chinese social network can tap U.S. capital markets, but American social networks can't tap Chinese consumer markets. Does that sound fair?
