In general, this is a topic that interests me quite a bit (check out: “How Do You Sign an eBook?“). I seem to remember Barnes & Noble talking about NOOK signings, but haven’t seen anything much about that lately.Â Autography presents a compelling option for iPad ebook-signings, that provide a more tactile experience, and have the added virtue of coming in handy when you don’t have a pen handy but want Obama’s autograph.
You can find out a bit more information on the Kindlegraph website, which also has a helpful video demo. (Twitter sign-in is required to request a Kindlegraph from the current lineup of books available).
It’ll be worth keeping an eye on how Kindlegraph develops and what direction it takes. It’s kind of a neat idea. I’d try it.
