Wikipedia is one of the wonders the internet has brought us, along with Google, Paypal, Facebook and Craigslist. This list goes on. But Wiki and Craigslist are special since they are founded by true visionaries and idealists who value free speech and free information above all else.
Wiki and Craigslist could easily have sold out and created some sort of subscription or advertising model to capitalize on their very useful web sites. But they didn’t. They make what they need to run the site and not much more in order to keep the information clean free of any ulterior motive, like a city park or library.
Wiki is especially like this. Please read this statement by Wiki founder and consider donating a couple dollars to support this very valuable source of global knowledge.
