Kindlegraph

My commercial alter-ego, Isabelle Drake, is pretty excited about the new Kindlegraph feature for Kindle ebooks. With this feature, readers can request a personalized "Kindlegraph" of any of the Isabelle Drake books available on Kindle.

This Kindle function does, in a way, give Kindles an interesting advantage over paper books. But is it enough to have an electronic signature? After all, the author doesn't touch the book and the reader doesn't have to meet the author to get the "signature."

So what matters most? Meeting the author? Having a personalized copy?

Maybe it isn't a matter of one, a paper book signed, being better than another, a Kindle edition kindlegraphed. Maybe it's just a matter of different. ?
