Patrick Mannion's Journal: Is Geeks fiction?

My Tutorial teacher (It's a class we have) I'm doing free reading. I'm reading Jon Katz's book geeks (half the reason I decided to come to Slashdot). But my teacher believes it's fiction. I don't think it is. I keep pointing out obvious points that it is non-fiction but she just kees not beliving it. Boy, this is a predictament.
