THE growing popularity of social networking sites like Facebook, MySpace and Second Life has thrust many of us into a new world where we make “friends” with people we barely know, scrawl messages on each other’s walls and project our identities using totem-like visual symbols.

Academic researchers are starting to examine that question by taking an unusual tack: exploring the parallels between online social networks and tribal societies. In the collective patter of profile-surfing, messaging and “friending,” they see the resurgence of ancient patterns of oral communication.

“Orality is the base of all human experience,” says Lance Strate, a communications professor at Fordham University and devoted MySpace user. He says he is convinced that the popularity of social networks stems from their appeal to deep-seated, prehistoric patterns of human communication. “We evolved with speech,” he says. “We didn’t evolve with writing.”
