Google has announced a new project where people can share their knowledge by providing a well-organized, easy-to-use tool, this free tool is knol (knol stands for a unit of knowledge).
Google is coming out with Google Knol (Knowledge) which is exactly what Wikipedia is all about. The Google Knol sounds like it may just be a whole lot of wheel invention. Basically, this is a knowledge base - where experts write up articles and users have a chance to benefit from the wisdom. In Knol Google will provide authoring tools, store the information, allow others to comment and suggest edits, add ads with the author’s approval, and provide traffic via their search engine.
