I agree that the effect matters more than the label, too. Perhaps even to the extent that we no longer need the terminology? I *think* Euan managed not to use the phrase Web 2.0 once in his talk. (Euan? Did you?) He definitely talked about innovation, I know he talked about collaboration, and he talked a lot about a culture of sharing. He gave some examples of tools, and everyone knew exactly what he was talking about. Web 2.0 was not needed.

Maybe Web 2.0 has already come to mean what we know is happening already, and what is described in that graph as Web 3.0 could just be what comes next (though I doubt it is a comprehensive prediction). Web 4.0, of course, by extension becomes whatver comes after that. :-)

I used the graph to illustrate the technology waves that wash over us at regular intervals. There is part of me that hopes that the ‘Semantic Web Technologies’, that he puts under the heading of Web 3.0, does get a better name.

Whatever the label is the effect that matters.
