Google Knol launched

Google Knol has been officially launched today. Each Knol is defined as a 'Unit of Knowledge'. Each topic has an author who has exclusive ownership of the topic and it is associated with the author.

The author can allow suggestions, changes, etc. but unlike Wikipedia, the author cannot be challenged. Long term there might be 'authority' associated with an author just as there is for websites. This will probably decide the rank where there are multiple knolls for a topic.
