Der Spiegel reports (original article in German):
Ab Juli wird dieser Pool nun nach konkreten Nutzungsstatistiken unter den Autoren aufgeteilt. Die kommen zustande, indem jeder einzelne Kindle-E-Book-Reader das Leseverhalten seines Lesers protokolliert und an Amazon zurückmeldet.
[translation mine] Starting in July, the pool of Amazon subscriber money will be shared among authors according to concrete usage statistics. The statistics will come from individual Kindle E-Books that will record reader behavior and communicate it back to Amazon.
Is this a model for content production in the future?

I got the article from Der Spiegel, Netzwelt section. I used their title. Perhaps your comments are better directed to "responsible" news sources like them.
Washington DC delenda est.
