This sounds super cool. I wish I'd known about it sooner. Currently, I have three novels published on Amazon, and I JUST got done posting another novel to Steemit (a chapter a day, with a 50-chapter, 104,000 word novel). I wanted to compare the Amazon and Steemit publishing experiences. If I'd known about this, I would have used it for my Steemit novel.
I've got a fifth novel in progress, but I'm only about a quarter of the way done with writing it, and then it will need a few rounds of editing.
Well... You could publish it chapter by chapter at your own pace 😁
