Very occasionally I'll pick up a one or two dollar secondhand book that I never get around to reading. Generally it's because I recognise the author and think I should taste their work.
However, I never buy a new book that I don't immediately gobble up. I have an intense reading habit.
This post is in the nature of peering over the fence at alien beings, people who buy a book so they can play a part in conversations about the book. Do such people exist or are they an urban myth? Do people really buy books by fashion, uncaring of what's between the covers?
