Many gleefully trash Wikipedia, but nonetheless it is one of the most helpful and practical resources on the internet along with Google search. While most articles are not eloquent prose, as a whole Wikipedia is the largest and best first stop when investigating a topic. It is a wonderful example of what people can accomplish when they work collaboratively. My hat is off to Jimmy Wales and all the others who created Wikipedia. It's a self sustaining information ecosystem that is constantly cleansing itself and making itself better and better every day.
Knowledge is power. Power to the people. It's as simple as that.
