I vaguely remember “The Nets” in Enders game but not how they functioned. What about Card’s portrayal did you find prescient?

Card's idea that everyone could publish and excellent voices would be amplified was correct in premise, though it's conclusion was completely off. Classic XKCD parodied it brilliantly IMHO: https://xkcd.com/635/
