OK, sorry for the awful pun. Knol (http://knol.google.com/k) is Google's answer/competitor to Wikipedia, and while it is currently in beta (like much of Google's other properties), I can begin to see some use in the system. Knol differs from Wikipedia in that you can see the authors of an article. So, if I want to author an article on the life and times of budgerigars, I simply need to create an account and publish. If (and this is the key) my article is seen as authoritive, and receives good ratings from other users, the article will get pushed up on the search results page. Knol also allows comments, so be prepared for some constructive criticism if you author on a popular or well-known subject.
It will be interesting to see how Google eventually integrates Knol into their Universal search results ... will Google end up placing Knol results above other resources, such as Wikipedia?
While Knol is still a work in progress, it may become another valuable resource for searchers. Stay tuned!
