Yesterday, Google
officially launched Knol, its Wikipedia-like tool for crafting encyclopedic expert articles. As with Wikipedia, subject matter experts can write or contribute edits to a Knol page on a specific topic. Unlike the case with Wikipedia, however, the author(s) is identified, so readers know who contributed to the article and understand any biases the author(s) may bring to the topic. For example, a technology vendor may write a very different page on a specific topic than what a user would write. Politically, a Libertarian is likely to define a term such as "healthcare reform" very differently from a Green.
