Knol is a new publishing platform in testing by Google. Compared to Wikipedia, Knol differs in one crucial aspect: authorial transparency. “Knols,” or pages, are created by one author who then has editorial control over the article. Other users may submit revisions to the author, but they may not edit the page on their own. Knol will include multiple pages on the same topic and will allow users to rate and comment upon individual “knols.” As of this writing, Knol is in a preliminary testing phase and there is no projected public release date.
