WikiLeaks is an astonishing community platform that publishes anonymous submissions and leaks of sensitive documents relating to governmental, corporate, or religious acts, effectively preserving the anonymity and untraceability of its contributors. Actually they claim to host 1.2 million documents sent by dissident communities and anonymous sources. It's an incredibly powerful tool for research, a priceless database for freedom of information and especially investigative journalism, and it should be taken into account that bloggers (especially) still have a different status from journalists. They avoided the trap of free posts, so they now check and edit everything, taking responsibility of what they publish. WikiLeaks mission is just to allow public evaluation of the documents and they have already proven bold enough to reject censorship pressures from giants like the Chinese government or the Scientology religious sect. And that's quite a remarkable attitude.
