J. Brandon, I like your idea of creating a separate publication for serial fiction. I accidentally started a serial story when someone “complained” that one of my stories was too short. So I offered to write a sequel. I am now working on part 4. It has been fun. Although it will probably only have a few more parts.
I think the idea would work great for a novel or a longer “short story” also. Releasing one chapter at a time. A publication makes it much easier to access than just being part of your writer feed. Although you are quite brave to do it while the work is still in progress.
Good luck!
