The original post is in Chinese, I found it interesting enough to translate it.
The author, Fenng states 3 laws of the Great Firewall of China. GFW. If you know nothing about GFW, please read the article on wired.
First law of GFW: Site with User-generated content will be harmonized1
Second law of GFW: Any site got harmonized will have a cloned [and way worse] version in China [Benefiting people who have no imagination at making their own stuff].
Third law of GFW: The site does not get harmonized is never the most popular site in it's niche.

GFW have killed wikipedia, flickr and more. and it's influence is getting larger everyday. This have to be stopped. Everything the people in China see is what the government wants them to see. A lot of people still believe the country is in it's best shape. This can never be accomplished since most people in China don't have the balls to go against the government. It's understandable. Anyone who does so will not just danger himself, but everyone close to him.
