Web. Web Social. Web Ubiqu. Web Singularity.
I guess most hackers don't like the term web/bubble 2.0/3.0 is because it's overloaded, and hence, imprecise. Thus, ripe for exploitation by marketers, which generally have a bad rep with hackers (sometimes with good reason).
I think the author just means "the next evolutionary step of the web" Just as when people are talking about 2.0, they just mean that the web now was far different than it was back in 1996.
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."
Do you think he's spot on, and know any reasons for or against it?
I don't think the web can grow much more complex without it outgrowing our ability (as both users and providers) to use it effectively -- at least not to its full potential. Therefore growth will probably have to be balanced by growth in our intuitive knowledge and competencies: education.
To me, it seems that the average user has to know less and less about the underlying web in order to use it to do things. Perhaps you're talking about people that build tools on the web?
Yet another article about web 3.0, blah.
