The thing that we can be sure about, is that the "people who do buy" these books are feeding a completely sustainable marketplace, one that has seen not a hair of gratuitious inflation, one that has seen zero reader drop off in the past three decades, one that is strong and thriving.
What we know to be the right course of action would be to take content, judge it on its success or failure in a dying ecosystem, and if it survives in this small Tabula Rasa in the middle of a desert, it lives. If not? We do not build new ecosystems. We do not find new ways to reach out. We do not let stories live for a while to find and build an audience outside of that little Tabula Rasa, where other organisms live and thrive, and sometimes peek in through the walls of that Tabula Rasa out of curiosity, and sometimes grab things here and there, pull them out, and give them new life somewhere else.
We don't do that, not now, not ever.
