I think if there hadn't been the one passage of the book that mostly abandons the humor, and focuses very intently on one person's struggle with cancer, it wouldn't have been a critical success. So that was a very deliberate decision, to say "Well, if you think it's all fun and games, it's not." So that was my approach: We're going to have as much fun as I can possibly provide, but the serious things that might normally pass by you are not going to be lost.

Why shouldn't it be that way for the rest of us? Why not just go with it? Just walk the dog and send the tweets and eat the scones and play with the hamsters and ride the bicycles and watch the sunsets and stream the movies and never worry about any of it?

'I'm touring college towns with my garage band.' We were dumbfounded. It was like they were from another planet. Where had they found the derring-do? What would they do about car payments?

The internet takes a lot of the anxiety of life away. It's a kind of deity. You're never lonely. You're always distracted. If you spend enough time on it, there's not really that nagging sensation of existential despair; it erases it very effectively. And it's monolithic. And thanks to it, we've got the ways to linger there after death - your blog exists afterwards, your e-mail exists afterwards.
