Well, it will all be in the book, but there are numerous studies of web reading vs. book reading that show the former are destroying the ability for “deep reading,” i.e., imposing any significant thought to the subject. Test subjects with a book and with a Kindle did far worse on the e-book when it came to understanding the plot, remembering key points in the story, and that verbal/language skills have deteriorated sharply among heavy net users.
I was just discussing this the other day with another FReeper.
