I, too, have taken the plunge into Kindle Vella. I've launched a science fiction serial called "The Belt." It's too early to tell how it will be received, but if anyone is interested in having a look, it's at https://www.amazon.com/kindle-vella/story/B09D6FWHLC. I'm writing it as I go along. I started with four episodes written and put a fifth one up the day after launch. I hope to publish a new one each week, although right now I'll probably also be writing a new one each week. Maybe over the next couple of months I can build up a stockpile and release them to a schedule. We'll see. Anyway, thank you for this timely article.
