Welcome to Citizendium
Help Write Articles about our World
Welcome to Citizendium, a wiki for providing free knowledge where authors use their real names. We write the kinds of encyclopedia-style articles that Wikipedia and other sites can't write. We welcome anyone who wants to share their knowledge on virtually any subject. Our online community prides itself on being congenial and supportive.
Our goals have changed. Please read about who we are in 2021.
See Recent Changes—an overview of articles we are writing now.
