Query: Maybe only a programmer can enjoy this book.

I was disappointed in this book because the characters were so sketchy. I could hardly tell one character from another until late in the book. The story seemed like a string of unrelated incidents, each one with little point. Every time Kidder would relate something going on in the computer lab, he would give so few details that it was impossible to get interested in the events. There was no definitive explanation as to why people were acting certain ways. Maybe you have to have "been there."
