Has there already been a lengthy discussion of the book series beginning with Ender's Game, and in particular the fourth in the series (I think) Shadow of the Hegemon and it's apparent prediction of the blogosphere?
If you haven't read it already, Ender's Game is a book written... oh, orignially I think it was 1977 or so as a novella and then re-worked into a novel in the mid-80s by a fellow called Orson Scott Card. Shadow of the Hegemon was written much later, I think published in late 2000. (To me, it seems like the movie Starship Troopers was made in the same universe, though sometime after the end of the first book.)
Anyways, the understanding Card has of the development arc of technology is pretty impressive (and the story's good, too.) In particular is the rise of global conversations held by individuals on the 'Nets,' and the subsequent political power certain individuals gather by analysis and debate of world events.
