The challenge of nonfiction is keeping the attention of a reader over span of time, and to keep the quality of the writing as high as it needs to be to keep people's attention.

It's surprising how a minor slump in sales can have a huge impact, and can actually cut so significantly into margin that the company really feels it.

I don't think people who are supporting the food movement ever want to be in a position where they are opposing the workers who are dependent on the system. The companies are very good at setting up workers and activists in opposition to each other, and getting the message out to workers that those people are threatening their jobs.

The pleasure of nonfiction is that it takes all of that sort of artistic and observational skill, but then there's a more intellectual layer on top of it: it's not enough to make us see things in new ways, we have to try to figure out what that means for the way we live.
