I scribble about programming because nothing digital has so far allowed me to use spatial arrangement, arrows and such to organize my thoughts as conveniently.

I very rarely write on paper anything more than a short sentence at a time.

For me, paper is less about writing and more about laying out my thoughts.

(So far writing on digital tablets has been a less than great experience and I really like the real world arrangeability and simultaneous viewing of multiple pieces of paper.)
