The above linked article isn’t talking about a new Kindle model, as I originally thought. It is a tool for authors to get their stories out as they are writing them. They don’t need a publisher. The stories can be published an episode at a time, and the reader has to pay for tokens to read the stories.
It sounds like a great tool for new authors. I’m not sure how well it would work for the readers, but it’s certainly a new idea.
