I've just heard about a new wiki that claims to be: "developing an uncensorable Wikipedia for untraceable mass document leaking and analysis."
The primary aim of the wiki is supposed to be about assisting people who live under oppressive regimes in Asia, the former Soviet bloc, Sub-Saharan Africa and the Middle East.
However, and this is where it gets interesting, a further aim is to offer a forms of assistance to those in the West who wish to reveal unethical behavior in their own governments and corporations.
If this wiki takes off anywhere near the extent to Wikipedia has, then expect it to mentioned more than once or twice in the coming months and years.
See Wikileaks for more details.
