How to monetize
First, I think there is an inherent difference between a casual project, a hobby, a pastime and a product. And a product it is, as soon as you want to earn money with it
Then, obviously, you’ll have to decide upon the way of monetization. There is a very broad spectrum of possible strategies, ranging from simply putting a price tag on your ‘product’ to not even selling this itself. Instead, merchandise (even digital merchandise!) connected to your publication activities might be the right way for you.
Last not least there is marketing. Don’t fool yourself into thinking that ‘the internet’, ‘social media’ or ‘word of mouth’ will do the job of promoting your publishing project for you. They won’t without you pushing it.
