I'm definitely excited by big ideas, both in what I write and what I read. Most days, reality is so mind-numbingly dull that I don't understand why someone would write strictly realistic stories, given the almost limitless freedom fiction provides. I don't see the point of making believe if you're not going to actually make believe: hang your ass out in the wind, push at every boundary, make almost unreasonable demands on your reader's willingness to suspend disbelief. This is dangerous, and prone to failure, but that's part of what makes it fun.
