Heh, I actually mapped my thoughts following Lion Kimbro's method, six or seven years ago; I still have the notebooks on my shelf. From what he later said, he doesn't really recommend it, it bogs one down.

I still think it was an interesting experiment, though I'd put it more in the category of creativity helper / mind map; it's also interesting to have a snapshot of the kind of stuff I thought about a lot at the time, with quite a bit of detail.
