Apparently, there's a significant rise in Holocaust revisionism in Europe. (So, for human rights organisations, the debate is one about freedom of expression versus hate speech).
It made me think about what google.cn & other censored search engines are doing, as ably demonstrated by OpenNet Initiative's Google China Search Comparison.
I'm fascinated by how, in web terms, a censored internet can create a gaping absence in the visible history and politics of a country. So kudos to jimmy Wales for the way that Wikipedia defies China's censors. Perhaps the activities of the censoring search engines should be labelled real-time revisionism.
