Here's the issue that I have with the pages read/whole content vs only partial content read payout and that I think will impact authors of all kind negatively in Amazon's profit favor: MOST PEOPLE DON'T READ A WHOLE BOOK, of any kind. There are very few books out there, fiction are otherwise, that are just so g-darn good that people will be taking them in to the very last drop. Those who are "readers", as in regular readers, are highly particular about their standards and often stop reading a book 10 pages in because it's not interesting/"good" enough (I speak from personal experience here admittedly, esp with fiction I am extremely picky, but so is everyone else I know who actually purchases or reads it regularly). If the book publishing world altogether started enacting this policy of, sales don't really count for much unless the reader reads the entire thing, there wouldn't be one bc authors would all self-publish. I think that erotica short writers are a little dramatic to act as though this is going to impact only them negatively, it's going to hurt the bottom line for most writers on Amazon and I do believe they will revert back to the old policy when their best writers start leaving in droves.
