I became a writer on, and for, the internet. I wrote blog posts before I wrote novels, or even short stories. When I wrote, I did so conscious that my reader might at any moment get bored and close the tab. I wrote with a sense of urgency that bordered (not unreasonably) on panic.
This internet affect is palpable, I think, in my first novel, Mr. Penumbra’s 24-Hour Bookstore. In my second, Sourdough, it’s faded—but it’s still there. The point is, I have always tended towards brevity. I have never barfed out 150,000 words, only to cut them back to 75K. I have never, ever written long.
