That's easier said than done. To make some of the mathematical equations work and be legible in several of my papers required a lot of subtle positioning; this was not helped by strict conference page limits or requirements for e.g. 2 column layout (which exposes a lot of weird issues with LaTeX's rendering, which then have to be dealt with). Knuth's original papers, lovely though they are, are much simpler. If you want an example, consider Figure 4 from http://sigwinch.org/Graham/papers/Interface%20Grammars%20for... which was really quite tricky to lay out. I don't have the source code with me right at the moment for some reason, but I recall it being very tricky to modify.

Perhaps this means we should be trying to do simpler stuff, but I'm pretty sure that's impossible in the conference driven world I found myself in.
