Wikipedia is something special. It is like a library or a public park. It is like a temple for the mind. It is a place we can all go to think, to learn, to share our knowledge with others.
When I founded Wikipedia, I could have made it into a for-profit company with advertising banners, but I decided to do something different. We’ve worked hard over the years to keep it lean and tight. We fulfill our mission, and leave waste to others.
Seriously? Would anyone really care if those harmless Google Text ads showed up on a Wikipedia page?
