Listen. I get it. My last novel and a half was written as a serial. I got the benefit of seeing the audience reaction, scene by scene, in real time. Not only is that helpful as an author, it's a great way to hone my craft. But it IS a crutch.
It's part of why I'm forcing my next novel to be a murder mystery, something that I categorically cannot write as a serial, and cannot allow myself to spoil by posting about it online. I am forcing myself to actually write the whole damn thing before I show the audience. Unfortunately for ME, I have written maybe my favorite character I have ever created, and I can't fucking talk about her. I can't make posts about how I think she would get really scared after a hit of ditch weed. That hurts me. It's hard.
