An Interview with Chuck Palahniuk
Found this interview on Bookslut. It's pretty good. I haven't actually read any of his books, though I want to, but he seems like a really cool guy. There's some good tips in there for you writers.
Some writers research in order to write. I write in order to research topics that interest me. Especially if I can meet with other people, in forums from illness support groups to phone-sex hotlines, and learn what other people know best. Every character (really, person) sees the world through a framework of education and experience that they're proud experts about. To write a character, find out what they know best, and THEN you'll know how they'll describe a "hot day." Or a "pretty girl."
