Online, look through John Baez's website,

Thanks -- I haven't found anything there yet, but there are so many
goodies on John Baez's site that I almost always get distracted
reading something cool <grin>

Try, for instance, here:

http://math.ucr.edu/home/baez/qg-fall2000/

Do other people follow this, use these notations, or use
something of similar? (As opposed to not using diagrams
as a primary or featured tool.)

You see diagrammatic methods applied more often in group theory (e.g.
as described in Baez's Fall 2002 seminar), or of course the Feynman
diagrams in QFT. In day-to-day work with linear or tensor algebra, I
don't see people using diagrams very much to do calculations.

One problem with searching for terms such as "Penrose diagrams" is
that people use this to reference his cosmology diagrams.

"Diagrammatic" might help you more here than "diagram".
