Ever wonder how Wikipedia maintains such a high degree of quality material on any given subject? They have an army of unpaid content curators. They also have you.
The all-volunteer team of curators is constantly checking new submissions to ensure they meet the rules that Wikipedia established that were designed to prevent self-promotion, that articles only reference reliable sources, and establish levels of 'notability' for things that get their own article. Those that don’t meet the guidelines, they remove.via www.flickr.com
