To help you share what you knowThe Knol project is a site that hosts many knols — units of knowledge — written about various subjects. The authors of the knols can take credit for their writing, provide credentials, and elicit peer reviews and comments. Users can provide feedback, comments, related information. So the Knol project is a platform for sharing information, with multiple cues that help you evaluate the quality and veracity of information.
The key principle behind Knol is authorship. Every knol will have an author (or group of authors) who put their name behind their content. It's their knol, their voice, their opinion. google expect that there will be multiple knols on the same subject, and they think that is good.
With Knol, google introducing a new method for authors to work together that we call "moderated collaboration." With this feature, any reader can make suggested edits to a knol which the author may then choose to accept, reject, or modify before these contributions become visible to the public. This allows authors to accept suggestions from everyone in the world while remaining in control of their content. After all, their name is associated with it!
