I have always viewed the mission of Wikipedia to be much bigger than just creating a killer website. We're doing that of course and having a lot of fun doing it but a big part of what motivates us is our larger mission to affect the world in a positive way.
The definition of marriage cannot be disputed. It's right there in black and white and it's been the same since the start of Wikipedia.
I'm quite good at taking in information so I voraciously inhale Wikipedia - which may have some things wrong in it but I think is generally more information than we had before. Last tour we didn't have Wikipedia. And then Discovery Channel and History Channel. I can take it in and retain what I think are the most important facts.
Wikipedia is just an incredible thing. It is fact-encirclingly huge and it is idiosyncratic careful messy funny shocking and full of simmering controversies - and it is free and it is fast.
I think I am done with Wikipedia for the time being. But I have a secret hope. Someone recently proposed a Wikimorgue - a bin of broken dreams where all rejects could still be read as long as they weren't libelous or otherwise illegal.
