books and compatibility

The new york times has an article on whether people have to like the same books to be compatible. I really don't think so. I mean, on some level, there has to be some intelligence there, but there are all different sorts of interests, and certainly it doesn't matter much of they know who Nabokov is, or some other arbitrary hoop you might want them to jump through. I personally think compatibility is a lot more complicated than it might appear, and if the interests or perceptions are the same on a certain level, then nothing else matters too much. After all, who wants to marry a mirror image of themself? Love is not directed by the rational side of the brain, which can be a little disconcerting.
Then again, whoever you like has to share some of your interests I would guess.
