Think you are an expert on a subject? Well, Google's got a proposition for you. Google's Wikipedia competitor, Knol, was opened to the public on Wednesday morning, according to the Official Google Blog. So-called knols are articles about specific topics written by experts on that subject. Google is partnering with The New Yorker magazine to allow any author to add a cartoon from the magazine to their knol. Knol authors can run ads with them, as well, and receive a cut of the revenue from Google. What makes Knol different from Wikipedia is that every knol will have an author, or group of authors, whose name is prominent. "The big difference is authorship is highlighted," Cedric Dupont, Knol product manager, said in an interview with CNET News. "In the long term we hope that encyclopedias, such as Wikipedia, would use knols as references... If Knol is successful, it will help Wikipedia."
Google Knol is a competitor to Wikipedia.
