To my way of thinking there is a continuum between highly tacit stuff and clearly explicit knowledge.
Tacit knowledge is closely related to intuition, gut feelings, compiled experiences and skills. This tacit stuff is very hard to explain, it comes from exposure, arises out of repeated learnings, consists of deeply held feelings and beliefs. Tacit knowledge allows us to reason without logic, to act without reflection and to make sense of new situations.
Implicit knowledge sits in the middle. Here we are able to model, explain, draw, surface, share insights and explicate beliefs. This often requires time, deep reflection, dialog, introspection and mulling around.
Explicit knowledge is documented, illustrated, captured, stored and retrievable. It takes many forms from transcripts, to business rules, from detailed definitions to evolving scripts e.g. such as we see in wikipedia or video sequences.
Not everyone will impute the same meaning to explicit knowledge,personal or group interpretations are context and time dependent and biased by each individuals own tacit knowledge.
The key is not finding a clear definition of explicit or tacit but wrestling with the meaning, exploring examples, situating knowledge along the continuum. For what is tacit now may become explicit tomorrow and what is implicit can easily return to the tacit well or source
These definitions assume knowledge is a thing, which is one valid view. How would you describe knowledge as a flow or process Denham? Whenever I've tried I end up giving example of knowledge as a flow such as social networks.

The reason they call it management is that they intend to exploit its business value. It isn't about building playrounds in the sky.

I can see how explicit knowledge (EK) is a commodity in a business value sense. But just as the meaning of EK can be affected by tacit knowledge (TK), why can't EK stimulate the emergence of TK, like when you read a book whose EK triggers the creating or modification of some deeply held belief, which then tacitly influences your behavior?

Most of the knowledge we deal with everyday is tacit. Even with the information explosion, most of the knowledge is tacit.
The business value of explicit knowledge or information is much lower than that of tacit knowledge. To explicate is to commoditize.

Well said, Denham. I've added your description of these knowledge types to to my DIKUW blog .
