Search behemoth Google has announced a new tool to rival Wikipedia. Currently known as “knol” (it stand for a unit of knowledge, apparently), its object is “to encourage people who know a particular subject to write an authoritative article about it.” This sounds very much like Wikipedia, although some would argue that you need no nothing about a subject to be a Wikipedia contributor (despite credible evidence that suggest otherwise).
Google has yet to announce when the general public will get to experience “knol”, but you can find out more and see a screenshot of the prototype here.
