Every so often, I see a plot post/meme/tweet/pagan incantation about what readers owe authors- reviews! Word of mouth! – or something along the lines of this:
“Because I want to keep writing  and the only way for that happen is for people to buy my books, to get reviews, and *liked* reviews.”

Which.. no, no that is not. The only way you keep writing is if you keep writing (Note: Tez is quoting from a newsletter there). You may or may not make some/much/any money from it, but that’s the definition, folks.
But let’s be abundantly clear about what a reader owes you: the price of the book. That’s it. If, for example, you wish to read *my* book (which you should- it has been favorably compared to Star Wars, Indiana Jones, Firefly and Twilight Zone!), you may purchase it for two dollars and ninety-nine cents, which you should most certainly do. Once you have done that, our transaction is concluded! I hope you enjoy it!
And, in the event that a reader does like it, I hope they do leave a pleasant review and tell all their friends that they should purchase said book as well. But they don’t have to. And so many authors see this as a must. But, friends, it is not. Do they help? You bet! I only have 16 reviews on my silly little collection, mostly favorable, and that helps. Is it the end-all, be-all of book selling? It is not. Does it have any bearing on my continuing to write? Certainly not. If everyone in the universe went and bought it and my next royalty check was for some absurd amount of money, or simply had more number to the left of the decimal place rather than the right, it would probably make writing more easier. But it doesn’t determine if I do.
Likewise, if you do not enjoy my book, I hope you keep your pretty little reader mouth shut and not tell everyone what a steaming heap of prequel-level garbage my book is, and leaving a scathing review that makes me want to never even think about words again. But you can do those things if you want! You don’t owe me jack beyond the two dollars and ninety-nine cents you spent on my book. In fact, if you want everyone who reads your book to write a review, you might regret that. I’m sure people didn’t enjoy mine and refrained from saying so. That is probably a good thing.
So authors, please, enough badgering. Market to people in a way that makes them want to buy your book, and write books that people will want to leave (favorable) reviews of. Stop worrying about how each review and each sale affects your career/sales ranking/ego/whatever.
