While traveling in Brazil last summer I stayed for a couple of days in an eco lodge a few hundred miles from Manaus. When I left, I abandoned a copy of a book I'd been carrying with me - don't ask me for its title - not only for the benefit of a lighter load, but, also because the owner of the lodge encouraged us to do so.

Other guests would definitely appreciate stumbling on a good book, in the middle of nowhere, he said, they could pick it up without any  preconceived notion, and it would take them places they'd never been before. Surprise them: an unexpected gift from one jungle visitor to another.

That my friends, you can't do with the Kindle. You cannot pass it on to a stranger...no you can't "Bookcross" a Kindle.
