Kindle's zero-sum reimbursement for authors means you're probably being gamed.
... the strange universe of Amazon Kindle Unlimited, where authors collaborate and compete to game Amazon’s algorithm. Trademark trolling is just the beginning:...
... unethical marketing and algorithmic tricks are running rampant ...
Authors like Suzan Tisdale, Zoe York, and Margaret Bates expressed the fear that book stuffing as a phenomenon was changing the culture of the genre. Romance, they assert, has gone from the kind and friendly, woman-centric atmosphere described by This American Life in 2003, to something scarier and more misogynistic.
I read 2 pages but still don't know what's going-on. Can someone explain it to me in simple concise language?
In brief, Kindle seems to be a platform which rewards authors for tricking readers. This degrades the quality of their offerings, and makes promoted material suspect.
Looking at the article...
Kindle Unlimited lets people read as many books as they want for $9.99 a month. "Authors are paid according to pages read, creating incentives to produce massively inflated and strangely structured books."
"...book stuffing plagues the romance genre on Kindle Unlimited, with titles that come in at 2000 or even 3000 pages (the maximum page length for a Kindle Unlimited book). That’s approximately the length of Atlas Shrugged or War and Peace.
Book stuffing is particularly controversial because Amazon pays authors from a single communal pot. In other words, Kindle Unlimited is a zero-sum game. The more one author gets from Kindle Unlimited, the less the other authors get."
All greek to me, I'm not in Kindle unlimited, & have no intention of joining.
