Wikipedia without question is one of our species greatest inventions. For 20 years a vast collection of entries has been created, maintained, and translated by an army of volunteer contributors through a model of open collaboration. The project carries no advertisements and is hosted by the Wikimedia Foundation, an American non-profit organization funded mainly through individual donations. For this reason, we will be donating 100% of the profit generated from this T-shirt to the Wikimedia Foundation to continue making this tool free and accessible for the world to use.
Let's not burn down the Library of Alexandria twice. Wikipedia is an invention worth protecting.
