Long live the book:Dialogue, handwriting, print, photography, cinema, radio, television, digital: all these things still exist, yet each of them in turn has become the defining media of an era, longer or shorter, only to have their dominance overtaken by the next big thing. None of them have wholly been superseded, because each has its particular communication that it is not only well suited for, but such communication is almost impossible in any other form.Debate might still be best done in person–at least the nature of debate changes through blogs and comments…. Philosophy and other extended treatise work well in the printed book but as Neil Postman writes, extended discourse just doesn’t work on television.The average time a reader spends on a blog post is 96 seconds.
