Like a wiki, it is designed in the original collaborative vision of the Web. Unlike most wiki software, it allows users to build their own distinct views of subjects without requiring users to agree on a single article. Instead it lets users with different views provide competing entries which can both stand on their own.
There is a public account, username 'Userpage/cypherpunk', password 'cypherpunk', which allows anyone to post an anonymous article under the same account, much like a traditional single-article wiki.
Do you stay awake at night, thinking of the things you should worry about?
