Encyclopedia Britannica Opens Up

It was announced earlier this week that Encyclopedia Britannica will switch to a wiki model, details are located here at Wired. The Encyclopedia has fallen from it's previous pedestal, and is now allowing contributors to edit it's material. In doing so, they're wishing to create an open community for scholars, experts and lay contributors.
There will now be three categories of content: content from the existing community of experts (via the new wiki model), content provided by Encyclopedia Britannica, and the combination of the two once facts have been checked and verified.
