"Can Cyberspace have Margins?"

Historically, print discourse is perceived as a space with a more-or-less clear center and margins, and this perception has been crucial to the formation of "imagined communities" around certain common experiences -- of what Samuel Johnson called "nations of readers." Electronic media, though, seem not to support this common spatial picture; the center seems to be everywhere, and the circumference nowhere. All of which leads to the question of whether electronic interaction on its own can sustain a sense of broad community in the way that print has -- or whether it has to.
