I just gave some money to Wikipedia. If you use it like I use it, consider doing the same.
I find that Wikipedia is often my first source for any information. And if the topic is contetious (Global Warming, South Ossetia, the Armenian Genocide), then I know I’m going to get information that was debated and agreed upon (eventually) by both sides. That works a lot better for me than a traditional encyclopedia or news source.
Some scholars dismiss the concept of “truth via consensus” as post-modern mumbo-jumbo. “No,” they argue. “Objective truth exists.” Well, I’m not so sure.
In the meantime, Wikipedia seems to be working pretty well.
