Big Brother Amazon

Last week Amazon released a ranking of books based upon the number of passages highlighted by readers of Kindle e-books. I happen to read e-books I buy from Amazon, and I have the habit of highlighting certain sentences I wish to remember. I don't think that is unusual. I find it highly unusual, however, that the company I buy my books from keeps track of what I read and registers which sentences I find remarkable. Nobody seems to mind. Several newspapers reported about the ranking based on the Amazon survey. None saw a problem in Amazon's interest in their users' personal interests. I do see a problem. I am upset. Maybe I am too sensitive, but I don't want to be watched by some big brother when I read a book.
