theodp writes: In Amazonia, e-Books read you! So, for an online performance piece, Berlin-based "interface artist" Johannes P Osterhoff decided to make a statement about privacy in the digital age, jailbreaking his Kindle and using PHP to automatically send an email to Amazon CEO Jeff Bezos whenever he sets a bookmark. 'Dear Jeff Bezos,' reads a recent missive. 'I just read Daemon by Daniel Suarez until position 478. Sincerely, Johannes P Osterhoff.' Explaining his motivation, Osterhoff said, 'Not so long ago it was very simple to read a book in private. With the Kindle and Whispersync it is impossible. I am required to surrender my privacy during reading on my Kindle. So sending e-mails about my reading activity directly to the CEO of Amazon was just the next logical step.' Not too surprisingly, Bezos hasn’t yet replied to the messages.
