Though I think it's a fantastic idea, one built around the concept of merchandising (a word people hate to use with books), B&N's rearranging of their teen book section is already pulling in derisive comments from the web.
I don't think this is any way the sign of the apocalypse, but rather an admission that readers of certain genres stick to those genres. They also buy a lot of books. And if this makes it easier for them to buy more books, I'm all for it.
What do you think?
