After reading Ender's Game, I liked the idea of "nets," and had some good ideas to put on there, but could never find them or what they are. Any idea, or is this just another fictional part of Ender's Game?
'Nets' are basically the Internet as predicted/guessed by Orson Scott Card
It is interesting to note that the World Wide Web, the modern form of the Internet, was not invented until 1990, 5 years after Ender's Game was published. Orson Scott Card accurately predicted how much influence the nets would have, years before they became a daily part of people's lives.
While there’s plenty of time for Internet discussions to turn around, I suppose, I can’t help but think that Card wasn’t terribly prescient with this prediction. In Ender’s Game, “the nets” are democratic and participative — anyone can join them, as long as they have the intellect to keep up — but there’s no problem with too much noise, trolls, spammers, and plain old stupidity.
