I agree that the terms are silly and abused, but unfortunately we seem to be getting stuck with them. I'd love to have better ones (know any?), but for now, you have to admit that people at least know what they refer to: things that'd otherwise be too ambiguous. These over-simple terms aren't bypassing consensus, they are a means to consensus-building.
As to the earlier comment, the whole point of the essay is that we need to look at fads as if they are bubbles, users as if they're investors. See Davenport and Becks 'Attention Economy' as well as Mark Anielski's 'Economics of Happiness'. And to see the where I'm eventually trying to lead, see David Warsh's 'Knowledge and the Wealth of Nations' and the 2005 World Bank paper called "Where is the Wealth of Nations."
