I love diagrams. I love them so much!

In fact, I have fairly poor visualization skills, so making a diagram is extremely helpful to me: I'll have some vague idea of how different things are connected, and then I'll make a diagram, and suddenly there's a tangible thing I can look at and talk about.

Of course the diagram only represents a fraction of what I had in mind in the first place, but that's okay: the point is to be able to talk about of a concept, and so I have to make choices about what to include in the diagram. And maybe make several diagrams.
