I do find this article very inspiring, and it lays out a crystal-clear vision. But again and again I wonder why these ideas didn't get more traction.
Of course, they're starting to be more widely accepted under the "web 2.0" umberella. And there were similar echoes in other smart people : Philip and Alex's Guide (especially http://philip.greenspun.com/panda/money ) and Dave Winer's "How to make money on the internet". Or even the phenomenon of sites like Slashdot, Kuru5hin etc.
But what stopped this stuff happening in the late 90s? Was it purely inertia and cluelessness of the mainstream media companies? Why couldn't mainstream media "dabble" in this space?
Why couldn't some startup have invaded? Think about the explosion in free, ad-supported webhosting like Tripod, GeoCities, FortuneCities, Angelfire etc. These should have been ready to carry the media 2.0 torch.
In a strategic sense, why weren't the ideas disruptive or capable of invading the status quo in the late 90s?
