"Google has just launched Knol to the public, dubbed by many as the search giant\u2019s Wikipedia killer.  My first reaction: not so fast.  While Knol offers a way for anyone to create content about any subject, there are a few big differences.\nFirst and foremost, each \u201CKnol\u201D is created by a single author, who can then choose to either accept or reject edits made by others in what Google is calling \u201Cmoderated collaboration.\u201D  Beyond that, Knol authors can insert AdSense on their Knols and earn revenue based on clicks.  In reality, this sounds a lot less like the community collaborating on authoritative articles (Wikipedia) and a lot more like a potential land grab to create content for lucrative keywords.  \n\n\n\n\nHowever, Google does offer some options that should keep would-be opportunists at bay.  Each Knol offers the ability for anyone to review or comment on it, which in turn raises or lowers the authority of the article.  Google says that they \u201Cexpect that there will be multiple knolls on the same subject, and we think that is good.\u201D\nIn giving a single author control over each Knol and its edits, it\u2019s hard to imagine the service will be as authoritative as Wikipedia (which, many would argue has its own biases).  It seems more like Squidoo, where knowledgeable people can create good content and be rewarded for it, with the community at-large determining how valuable it is and recognizing that there may be some bias in the article.  \nMeanwhile, Knol could still be a huge traffic generator for Google and steal visitors from Wikipedia if it\u2019s integrated in search results \u2013 something Google has not been shy about doing with other properties like YouTube.  \nGoogle company profile provided by TradeVibes\n"^^<http://www.w3.org/2001/XMLSchema#string>
