Enterprise 2.0

A great presentation by Paul Kedrosky on Enterprise 2.0. I particularly liked the quote:
"The opposite of an imposed structure is not chaos. With Web 2.0 tools, the opposite of an imposed structure is an emergent structure, one that forms over time based on the interactions of a lot of people."
Andrew McAfee,HBS
The presentation is well worth reading, largely for its valid deflation of some of the hype around Enterprise 2.0 as an idea.
My own view is the key to Enterprise 2.0 is not in the technology or usage, but by the sales process.
