comment Why isn't the identity matrix upright?
@egreg Thanks! I too have a problem with closed standards. I'm looking at the NIST std. and it seems to not only to be consonant with my taste, but doesn't diverge much from ISO/IEC for the sort of mathematics I am writing. Unfortunately, that is because it is quite incomplete. It is very focussed on the formatting and printing of measurements rather than notations for pure mathematics. I do both---mathematical studies, and empirical investigation, but I'm largely covered on the measurements front by using the siunitx package.

ISO 80000-2:2009, Quantities and units---part2: Mathematical signs and symbols to be used in the natural sciences and technology would agree with Elsevier in this matter.

comment How should imaginary numbers be typeset?
This conflicts with ISO 80000-2:2009, Quantities and units---part2: Mathematical signs and symbols to be used in the natural sciences and technology. You could argue that we don't need to follow standards, but the confusion my students feel and the massive cost of accidents from misunderstandings related to notation and convention, demonstrates empirically that this isn't true. You could argue that it doesn't have to be the ISO standard, but it is already in wide use, and makes good choices in places where the only argument for convention would be an emotionally biased one.

comment pgfplots: select number of divisions
I didn't realize the syntax for ytick could be so nice (That is, {1,...,#4}). When I posted, I was playing with \for from tikz, which I doubt would have worked. Thanks a lot.

comment Seemingly simple block matrix
I see what you mean now, WRT (Q3). I agree, and perhaps will do it. This was the motivation behind defining these Js in the first place: they are large and unsightly. WRT (Q1), This basically means combining my last attempt from last night (the edit below my original post) with your fantastic \mc trick. I tried it, and works famously. Thanks.

comment Seemingly simple block matrix
(Q2) I meant the extent of the raisebox, so one needn't manually adjust. (Q3) You mean to beautify the code, rather than the typeset product, right?

comment Seemingly simple block matrix
Thanks, this seems to get me what I want. When I added content to some of the zeros, it pushed the Js out of alignment, which I manually adjusted. Q1) How did you arrive at .6\normalbaselineskip? Q2) Can you think of a way to make the spacing automatic? Q3) Could you elaborate on your final comment about assigning labels to components?
