Since the debate has begun anew, I again want to appeal to the designers of LaTeX 3's diagram package to be mindful of the needs of *ALL* likely users who need diagrammatic algebra. One should certainly be able to handle 2-categorical diagrams as in Karponov and Voevodsky's recent work, as well as Joyal/Street "string diagrams" (and with them at no extra cost, except allowing the user to specify straight, dotted, double, or wavy lines with or without arrows, Feynman diagrams, knot and braid diagrams, the "Chinese character" diagrams arising in the theory of Vassiliev invariants, and linear logic proof nets). Algebra loosed from the constraints of living in strings of symbols was once the exclusive province of categorists, but no more, we are now joined by low-dimensional topologists, theoretical physicists, and a host of others. Let's not build a tool for the needs of the early 1980's when by 2010 half of mathematics will need what some in this debate had derided as extravigances. --David Yetter +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
