Yesterday Google unveiled Knol, its answer to Wikipedia. Like Wikipedia, it’s a collaborative site, but there are differences: although a collbarotive site, meaning people can add to articles, each Knol, or piece, will have a primary author, who can choose to become a verified subscriber. And, perhaps more importantly, authors can earn money through Google AdSense, although including that with the article is at the discretion of the primary author.
According to Information Week, the author will also have to approve changes made by others, which means it knowledge base could escape the abuse that’s plagued Wikipedia.
