Wikipedia: often quoted, often defaced, often ridiculed, often found to be used as a credible source of information by major media organisations even though it contains erroneous information, and often to be found lurking at the top of Google’s search results for any given search phrase.

It seems that Google wants to dive into this world of collaboratively edited encyclopaedias with one of its own.

Currently being tested behind closed doors, with a selected group of people, “Knol” is a new service which sounds eerily like Wikipedia.
