I loved this post. And I think a focus on the flow of knowledge is crucial.

It's interesting that you mention Dave Snowden. His post on defining Knowledge Management (http://www.cognitive-edge.com/blogs/dave/2009/09/defining_km.php) is in many ways similar in tone to your post. Here's a comment I made on that post:

"...it's a good definition.

But, only half in jest, I've put a tweaked version below. (I've changed four words and phrases from KM to Training etc).

The purpose of the Training Department is to provide support for improved decision making and innovation throughout the organization. This is achieved through the effective management of human intuition and experience augmented by the provision of information, processes and technology together with Knowledge Management programmes.

The following guiding principles will be applied:
All courses will be clearly linked to operational and strategic goals

As far as possible the approach adopted will be to stimulate local activity rather than impose central solutions

Co-ordination and distribution of learning will focus on allowing adaptation of good practice to the local context

Management of the L & D function will be based on a small centralized core, with a wider distributed network"

Is Learning & Development entering into a turf war with Knowledge Management? :)
