But would the lubricant make it worse thus counter acting the benefit of triggering the quake sooner?

Personally I use Libby and my library. Occasionally I've had to buy a book. I knew about libro.fm for a while because they market themselves as competitor to audible. But after we got some real numbers from Sanderson. I was curious because he never mentioned libro.fm. Considering the competition and the numbers Sanderson quotes I wonder if libro.fm isn't much better for authors. Afterall Libro is committed to splitting profits with partner bookstores. So if Libro's model is sustainable they need a larger share of profit. Who loses? I don't have the answers to these questions. And I would love input from industry insiders. But I can't believe the authors are getting a much better deal than they do with audible. The only benefit for authors choosing Libro in this hypothetical is that only audible (and kindle for that matter) pressures authors into exclusive deals. I find those deals to be particularly heinous since they exclude libraries during extended period upon release.
