The 'Green Dam' is a farce, a distraction! All data on the net is monitored and filtered by the central government, with or without the green dam... Just open up google.com and in another window open google.cn and type in "tiananmen square" and compare the two... This is just a basic example. My chinese friend showed me a Chinese computer site and he wrote a comment on there which included the phrase "central government tiananmen" and when he hit the save button he got a pop-up stating that his comment could not be posted due to "inappropriate" language. It's unreal!
