I think Daniel Green is just about spot on here when he says the there already is a "reading class." The vast majority of people don't read books for pleasure. That's just the way it is.
Maybe comics can help reverse the trend, though.
Can the "all you can eat" subscription model work in the world of eBooks? Or is it a bit foolish? I actually think it's not foolish; Esposito is right to point out that most book-lovers already have "way too many books to read", however, there's something to be said about a simple subscription fee that would allow you access to all the books (or at least a whole lot of them) from a hand-held device at-will. Think of doing research with such a device. Or skimming through parts of books—no need to go to the library or hunch down in an aisle of Barnes and Noble. Think of anytime you wanted something more to read you'd just pull out your device and pick any book at all, instead of having to be at home with pounds of books to sift through—think of traveling with such a device instead of having to schlep books from place to place. I would leap at such a subscription.
