I'm sure I'm even farther from being a GIS expert (and probably farther 
from one as well :), but I think you raise an interesting point.  My 
compass would give me directions at the geographic north pole, given 
that the magnetic north pole is different from the geographic north 
pole.  I'm curious how valid it would be to use magnetic north to assign 
directions at the geographic north pole.  My guess is not very valid, 
but kind of cool nonetheless.
