This is probably very similar to Patreon, and we'll have to look very closely at its success if we move forward.

My understanding is that when you pledge on Patreon you sign-up for a recurring subscription and then author then produces the work. You then have to unsubscribe if you no longer care about the authors work.

On this platform, the content would already be written ready for you consume. If you are enjoying a novel, you can pay to unlock more content immediately. You are not committing to a subscription, instead you are making a one time small purchase.

I think this can be better for authors too, because if somebody discovers an author with a large back catalog, they can go back and buy all their old premium content.
