No. Firstly no, the Network is just that, it's technology, you're describing culture, and the culture is a choice made by people of how to use that technology.

But also, this idea that somehow now that one guy who believes San Francisco doesn't exist is "media" whereas in 1990 he's not is insane. That's a choice you've made to re-define "random crazy people" as media, the Internet didn't do that. If anything changed magically in 1995 it's how you defined what does or doesn't count as media.
