Here's an article from the New York Times about "dealbreaker" lit. I'm not too much of a book snob because I read some pretty low-brow stuff, but for me, the dealbreaker would be someone who thinks The DaVinci Code is well-written. Or someone who read and followed The Secret. Although that would be more of a life-outlook problem than a literary problem. I'd just be happy to find a man who reads regularly...I don't know any. Do any of you have dealbreakers?
