I'm okay with this so long as there's absolutely no identifying information that goes along with it.<p>Having said that, if I had a kindle, I guess I'd start highlighting every obscenity.
If they made this opt-in, it would be great. When I read a physical book, it is a private thing and to maintain the integrity of the experience it should be opt-in.<p>That being said, I would be interested to see the results of what people are highlighting -- especially if they highlight and comment. I have also thought that the kindle should have a "Fire Notes" (kindle + spark notes = fire notes?) where you can download it and hook it onto the file and have the notes within the book. It would be great for classes and independent readers.
The headline you've given it makes this sound like they are sharing the info of individual users.<p>"The service doesn’t say which sections of which specific books a reader has highlighted..."
