I feel I was "pranked" by my "reading French for grad students" instructor. Assigned was a discursively long letter by Pascal to translate. The initial excitement of getting to read some Pascal wore thin as the letter went on and on and on. All was forgiven when I got to the end and read for myself the source of the famous "Sorry this letter was so long; I didn't have time to write a shorter one" (or something to that effect -- it's one of the nodes in the graph).

That was a great lesson on several levels.

Pascal's letter was an info dump, not a concise expression of an idea he wanted to convey. In editing, you start with the info dump and remove the unnecessary until you have clear simple statement of the ideas. All of this takes work, and mainly culls the unessential from the info dump.

Maybe the point of the page, is that the ideas have been culled, distilled into a simple little graph, resulting in even less writing?
