I've always felt like constructing printed math was much more of an art form than regular typesetting. Someone typesetting mathematics is less a "typist" and more an artist attempting to render abstract data on a two-dimensional surface. Mathematical symbols are themselves a language, but they are fundamentally a visual representation of human-conceived knowledge -- knowledge that would be too inefficient to convey through verbal explanations.
