I use Wikipedia as basically an extension of my brain. I'm in a history program at university, and so many of the names and dates that are essential to it I don't actually know. I realized this when I was writing something last night. I was writing about the English Civil War, and the Restoration, and I wanted to comment on the relationship between Charles I and Charles II, and I went to Wikipedia...and it was down!I had to go to my shelf and get a book. Who does that?
