Mass Media, Cyberculture and Effects on Human View

Each of these articles alludes to the idea that reality is the mixed compilation of different perceptions for humans of space over time (or to go one dark step further, is there any truth or just manipulation?). Inter-textuality is a fascinating component of movies, writings and music – and the Internet. Is the Internet of today, which is markedly different in substance and use than it was in the late 90s, subject to the same inter-textuality concerns within the Internet itself and all media forms in general?
Building on some past discussions from class and other theorists (like McLuhan), if human (individual, societal and cultural) development is in some way a function of mass media, does the Internet contribute in a new way to humans developing a “boundless” geographical mental view as opposed to the linear view we take in through reading and other media? How does the “self-created” web experience differ from the ready-to-eat media vehicles in conveying culture, sense of place, values and societal norms? And to what degree should we be measuring cyberculture in physical and virtual places?
