My friend Hilan complains that I'm structuring some of the arguments here in a way he doesn't find compelling. I tell him he can always refactor or offer an alternative structuration of the problem.
In doing so I explain the origin of the term "refactoring" and I see again how wiki derives from ExtremeProgramming
In practice, wiki isn't as easy to refactor as it would seem. Some of the ideas in SmallestFederatedWiki were interesting (dragging cards around.)
I have something similar but less slick in CardiganBay (card-oriented movement but still no dragging)
