He started out with good technical detail, but he is the first to admit, on his blog, that his technical details improved from the feedback he got from readers of his blog. He had scientific error in numerous places, which were caught by readers of his blog, and he made the corrections. This is what he had reported--you guessed it--*on his blog*.
One last time, what worked for him might not work for others. I'm simply sharing that Andy Weir published on his blog sections and chapters of "The Martian" before he published it as a complete book. He reported on his blog that he attributed his story's success to the feedback from that experience.
I have been working on my first novel for a while and have about 16000 words, probably about half of the finished book. I am wondering about the possibility of publishing it one chapter at a time, maybe with the first chapter free and then a small price for a limited period of time for succeeding chapters; at the conclusion of which I would publish download and hard copies of the entire novel. I think Stephen King did something similar to this with The Green Mile - not sure how successful it was. Any advice or suggestions?
My advice would be to finish the book, let it sit for six months, then revise it, perhaps joining a critical circle of like-minded authors who will critique it. Then circulate it to authors' representatives (aka agents) in hopes a reputable publisher will pick it up. People here love to sneer at "trad" publishers, but for every dollar you can earn on your own, Doubleday will earn you ten. (Doubleday will also abandon you faster, probably when your earnings drop to to the maximum you could hope to earn on your own. THEN you can think about self-publishing!)
Knowing you won't follow that advice, I turn to Plan B, which is to finish the book before you inflict it upon an unwary world. Many or most of us have tried this one-chapter thing -- I certainly have! it seemed the perfect way to exploit the ease and cheapness of ebooks -- but gave it up after three chapters. I was paying $40 for the covers and not earning it back. Nor have I ever seen a post here or on Kboards Writers Cafe (a good place to lurk, BTW) from someone who made a success of serializing a book. People are no longer willing to space out their entertainment, which is why even the stuffy old Public Broadcasting Service made Ken Burns's Vietnam and The Crown available for binge watching. Even Susan watched The Crown on ten successive nights.
(Don't trust KDP to publish a print edition. Don't trust CreateSpace to publish an ebook. Each does one thing well and the other thing poorly.)
