I first met Jimbo Wales, the face of Wikipedia, when he came to speak at Stanford.
Wikipedia is kind of extreme, where a very, very small group of people contribute pretty much everything.
When you look at Yahoo Answers, there can be a lot of garbage. But if you're careful about the rules and supporting good contributions, over time you can get better and better, like Wikipedia.
Don't believe anything you read on Wikipedia!
Wikipedia was a big help for science, especially science communication, and it shows no sign of diminishing in importance.
I did a series in Britain years ago called 'Skins,' and I remember my little sister telling me that I had a Wikipedia page that was talking about me. But then it got deleted because on Wikipedia anyone can write stuff, right? So I think that it got sabotaged. But this is years ago, so it got taken down. I don't think it exists anymore.
There are loads of fan sites for the 'Edge,' including deviant art, song lyrics using 'Edge' language, multiple entries on Wikipedia, there are even some 'Who Wants To Be A Millionaire?' games all about the 'Edge.'
We always talk about how the first several seasons were faithful to the books, and anybody who wanted to could go onto Wikipedia and learn Ned Stark gets beheaded or about The Red Wedding, and most people don't want to know - because why ruin a story?
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.
