Lucas McDonnell has some interesting comments on what I have to say on KM 2.0 and "2.0" in general.
I understand his concerns. I too was hesitant, at first, to apply the "2.0" moniker more widely to KM and other areas. But I have come to believe that although it all started with Web 2.0 and the new participatory technology and tools that it is not just about the technology and that we are moving to a "2.0 world" - a more participatory one.
I feel that far from devaluing the "2.0" concept - it expands it and makes it more powerful.
And of course I agree, 2.0 is not the answer to everything and brings as many new problems as it answers old ones. That's the nature of things!
