Everyone wants you to share. Share the music you listen to, the movies you watch, the articles you read, the books you read. So Johannes Osterhoff is sharing, just with the guy in charge.
Osterhoff's "performance" piece is to send Jeff Bezos a personalised email every time he sets a bookmark on his Kindle. The Kindle automatically generates the message, and sends it to both Bezos's publicly available address, as well as anyone else who's subscribed. It's kind of wonderful on all levels.
