Has "the architecture of the web" really changed away from "peer to peer" towards - what - centralized or top-down? In what respect?
Is the existence of Netflix and Facebook a threat to 1990s style Geekdom? Don't these modes of approach exist side-by-side?
"the industry structure seems much more oriented to mass entertainment"
Setting "mass entertainment" aside for a moment, it seems to me there are larger industries catering to other needs than the 90s ever dreamed: scientific inquiry, literacy, accessibility, communication, environmental protection, disaster awareness and relief, poverty alleviation, among others have all risen because of the internet. Those, and mass entertainment too, have all been driven by the interests and focus of Geeks, as I see it.
Am I wrong? Did I misunderstand something?
