As keynote at the Frankfurt Book Fair, Joel Stein, co-director of the Institute for the Future of the Book and founder of Social Book, said that he aims to turn reading from a solitary pursuit to a networked experience, where readers and authors can read books together, in constant communication, transforming the book from a staid object in the print era, to a live, active place online. All well and good. But some of us still want to just read a book, indulge in the singular enjoyment, create our own mental images, escape from the everyday world. What about you?
