Welcome to Citizendium

Natural Sciences     Social Sciences     Humanities     Arts     Applied Arts and Sciences     Recreation A 15-year experiment in a Wikipedia-like setting Welcome to Citizendium, a wiki for providing free knowledge where authors use their real, verified names. We welcome anyone who wants to share their knowledge by writing and improving articles on virtually any subject. This wiki was unsuccessful in achieving its original goals (see https://www.quora.com/What-is-the-difference-between-Wikipedia-and-Citizendium). A dedicated few writers have continued working in the wiki, improving articles that they believe are useful, and which for various reasons probably could not be written in Wikipedia. On or about Sept. 30, 2020, we plan to end Citizendium as a public "open" project, yet (possibly) keep the wiki running and editable by a combination of donations and subscriptions. How this might occur is still being examined. See Recent Changes—an overview of articles we are writing now. Join us Join here and start a new article or improve existing ones.
