Knol makes it easy for you to write and share your knowledge with the world

The 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 reviews and comments. Users can provide feedback, comments, and 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.

Knols are indexed by the big search engines, of course. And well-written knols become popular the same as regular web pages. The Knol site allows anyone to write and manage knols through a browser on any computer.
