writes "A report written by a tech worker in China describes the pervasive censorship, abetted by ample manpower and funding estimated at $27 billion in US dollars. The author, who calls himself Mr. Tao, also writes that plenty of Chinese are finding ways to resist censorship, and offers tips on how to keep evading Big GeGe (that's Older Brother). Not surprisingly, self-censorship is very prevalent. Also not surprisingly, the authorities are starting to catch on to things like RSS feeds. It's another race for survival between the tiny mammals and the lumbering dinosaurs."
Here's Mr. Tao's report
