I think graphically, which is why my book has lots of figures. Now that the manuscript for the book is about to enter production, I've decided to start producing short (~5 minute) video podcasts (vodcasts?) that contain tips about using agile.
You can find my first one, about using Scrum to pull work rather than to push it through a sprint at the bottom of my home site. Let me know what you think and how it can be improved!
