Nick Hornby, who made list making in novels a popular technique (I liked his 'About a boy' the best) says:

• Actually, when you think about it, not many novels in the Spare tradition are terribly cheerful. Jokes you can usually pluck out whole, by the roots, so if you're doing some heavy-duty prose-weeding, they're the first to go. And there's some stuff about the whole winnowing process I just don't get. Why does it always stop when the work in question has been reduced to sixty or seventy thousand words--entirely coincidentally, I'm sure, the minimum length for a publishable novel? I'm sure you could get it down to twenty or thirty if you tried hard enough. In fact, why stop at twenty or thirty? Why write at all? Why not just jot the plot and a couple of themes down on the back of an envelope and leave it at that? The truth is, there's nothing very utilitarian about fiction or its creation, and I suspect that people are desperate to make it sound manly, back-breaking labor because it's such a wussy thing to do in the first place. The obsession with austerity is an attempt to compensate, to make writing resemble a real job, like farming, or logging. (It's also why people who work in advertising put in twenty-hour days.) Go on, young writers--treat yourself to a joke, or an adverb! Spoil yourself! Readers won't mind!”
