FT.com - Wikipedia founder plans rival

"One of the founders of Wikipedia is days away from launching a rival to the collaborative internet encyclopaedia, in an attempt to bring a more orderly approach to organising knowledge online.
Wikipedia – which is available to be written and edited by anyone on the internet – is one of the most visible successes of mass collaboration on the web, with many of its 1.4m articles appearing high in search results.
However, its openness has also drawn charges of unreliability and left it vulnerable to disputes between people with opposing views, particularly on politically sensitive topics."
