Amazon already collects much of the mentioned data with its Kindle books, and has been doing it for years. I thought it was information that Amazon might 'sell' to publishers but, with an often adversarial relationships with publishers, and having their own lines of published books, maybe not so much. I think that data will be used by big publishers because with the increased competition created through smaller publishers and self-publishing authors, the large houses have to have a greater percentage of hits as compared to misses, to survive in the long run. Link to a 2010 blog post where I discussed some of this, including the link to an NPR article: http://uparoundthecorner.blogspot.com/2010/12/e-books-are-you-content-and-your-actual.html
