"Make/Think Sketchbook"

In her article "Make/Think Sketchbook" Carolyn Sewell displays her "notes" on an AIGA conference. Instead of writing out every little important word, Sewell sketched the facts that stuck out in her mind.  I do wonder, however, if she drew all of that at the conference or if she came back later and sketched everything. Nevertheless, the sketchbook of notes is awesome; I wish I could take notes like that.
