My question is, how does nonfiction stack up to fiction when it comes to sustainability? I'm not asking if fiction sells compared to nonfiction. We already know the answer. My question is one of sustainability. If you're a Kindle publisher, you probably would know that when you do the special Kindle promo you get a nice burst of sales and then it dies off slowly until you do your next KDP select freebie giveaway.
Is the sales pattern more predictable and sustainable for fiction compared to nonfiction?
