Dave, in thinking about how a MOOC approach with clients I’ve worked with, maybe the “M” part needs downplaying.

By way of analogy, for most workplaces, Wikipedia is probably the worst possible example of collaborative collection of information. Anyone who sees the wildly varying quality — to say nothing of the endless talk-page disputation — is likely to think “that’s not what we want here.”

(I treasure, on my own Wikipedia page, a comment to the effect that the original name was “Unemployed PhD Death Match.”)

And it’s not, because at the typical workplace you’ve got a closed, or at least selected, community from which the potential contributions will come.
