What I thought was important may not be what you thought was important.

I read a lot of Kindle books. My wife and I have written a book available for the Kindle. The "Kindle model" offers some capabilities that are under appreciated and often unknown to many readers.

For example, I am interested in the potential of sharing highlights and annotations. I have taken the time to highlight and annotate our own book and the books I assign for me graduate classes. 

I have a new fascination. I was searching our Kindle book for a specific reference and discovered that I can now view the most frequently highlighted passages by readers. Do the readers highlight the same content as I highlight? Do they highlight what I think is more applied content or content I would describe as conceptual and likely to be unfamiliar. There must be something here for deeper analysis. I had thought shared highlights was something I could share or readers could share with each other, but now I see value in the annotations as feedback to the author.
