Caltech graduate student Virgil Griffith just launched an unofficial Wikipedia search tool that threatens to lay bare the ego-editing and anonymous flacking on the site. Enter the name of a corporation, organization or government entity and you get a list of IP addresses assigned to it. Then with one or two clicks, you can see all the anonymous edits made from those addresses anywhere in Wikipedia's pages.
Wired is collecting cases of Wikipedia edits coming from those who stand to lose or gain depending on the accesible information. Several are already listed. They invite anyone to contribute cases you know of, or that you can find via Griffithâ€™s search tool. http://blog.wired.com/27bstroke6/2007/08/vote-on-the-top.html -via Metafilter
So why a company, for example, would not try to "enhance the truth"? Let's say Mattel enhancing the truth on the toy safety fight, instead of speaking of Chinese labor and environmental concerns... Even if it's not corporately organized, it would be every employee interest that his company is best presented to the world.
As long as you'll have counter-powers like the Griffith tool, you'll keep Wikipedia a *balanced* work, which makes it partial in the end.
Let's keep an eye open.
