I used to ask way too many questions as a child, though surely not as many as my own children. My Gran would silence me by saying "'Cause y's not z," and my Granddad would ask, "How long's a piece of string?"
I'm hosting a Second Wind Publishing discussion on Facebook and Goodreads where I ask how long's a novel, novella, novelette, short story, etc... and invite you to to wonder where dribbles and drabbles and chapters and blurbs fit in. I think my biggest conclusion so far is I'm still not sure if my e-book's a short story or a novella, but I'm convinced I'd find it harder to sell as a short story. Somehow short, and pay real money for it, don't quite fit together. But what do you think?
