Bookish Musings: Why I Don’t DNF Books

I was commenting on Aralyn's post over at Paper Addictions & Magic about why people might DNF books when I realized just how often it seems I find myself trying to explain why I don't DNF. And so I figured, why not just make a post about it? It seems I'm in the minority with this (nothing new there), so it might be good to have an explanation out there to explain to all the DNFers why us...
