I know I said Wattpad was awesome. I know I was excited about Kobo and Itunes. But Wattpad lost steam pretty quick. And Kobo had no sales. So, right now, while I can afford to, I'm experimenting with being exclusive to Kindle. When I have a strong fanbase across all platforms, I won't have this luxury, but right now I can.
We'll see if I get any boost in sales as a result. So far, not much difference, but I have yet to use Amazon's promotional tools.
