wikipedia

Wikipedia will be using the Ubuntu Linux distribution to power its sizable server infrastructure, report numerous sources. The popular online knowledge repository will try to create a homogeneous server environment in an attempt to reduce complexity and costs. The Linux flavor of choice is the Hardy Heron 8.04 long-term support version.

Google released its own version of a free online encyclopedia. Currently, Wikipedia is the undisputed leader in collaboratively edited content, with 2,400,000 articles in the largest English edition, and scoring tens of millions unique visitors every month. Google's Knol will rely on experts in specific fields to edit articles, rather than open the process to the anonymous wide public.
