I've known for a while that I write short (for a novelist). I've done five major story first drafts now, and they've all topped out between 30,000 and 35,000.
I'd come to the conclusion that I write short, but I'd never embraced it. I squeezed two novels out of the first two ideas. The next two still haven't been polished, for various reasons, but one of them was my partial reluctance to face the daunting task of adding more material (the other is, they're still simmering; that happens too).
But now, I'm going to embrace it. I write short. My new experiment consists of a set of episodic content spanning a longer story arc. The rise of indie ebook publishing, and the success of other episodic content by names more well-known than me lead me to believe there's a market for this type of thing. We shall see.
Episode 1 is drafted. I suspect I'll write one or two more before polishing the first, and embarking on a release cycle. Should be fun!
