Those who are shocked that the government of the PRC has clamped down on communications and social network internet sites are hopelessly naive. Given other crackdowns on dissent such as during the Olympics; this crackdown should have been expected.
However I do not think the situation is hopeless; I think it is possible that when the 100th anniversary of Tiananmen Square occurs that perhaps there will be a statue erected to honor the memory and the example of the brave man who stood up to the tanks. Will it happen; maybe; maybe not. The PRC is better now than earlier times; will the liberal values of free expression and free markets be more fully realized in 80 years? I hope so.
