An appeal from Wikipedia founder, Jimmy Wales.

Wikipedia is built differently from almost every other top 50 website. We have a small number of paid staff, just twenty-three. Wikipedia content is free to use by anyone for any purpose. Our annual expenses are less than six million dollars. Wikipedia is run by the non-profit Wikimedia Foundation, which I founded in 2003.

At its core, Wikipedia is driven by a global community of more than 150,000 volunteers – all dedicated to sharing knowledge freely. Over almost eight years, these volunteers have contributed more than 11 million articles in 265 languages. More than 275 million people come to our website every month to access information, free of charge and free of advertising.
