Knol a wiki

Google offers a new service called Knol that will capitalize on the growing popularity of "social encyclopedias" like Wikipedia.

Like similar products, Knol users will be able to create a page on any topic with information, pictures, links and more.

Google's primary focus with Knol is the authorship of each page. The original creator of each page will have a miniature profile on the page and will be given options to control the page. One significant difference between Knol and competing services is that authors have the option to place Google ads on the pages they manage and receive revenue from those ads.

The author of a page can limit what other users can modify on their page. A comments section will always exist allowing users to comment, but actual changes to the content can be limited by the author.
