I definitely agree, but still, a lot of people are told "you will never use your math or writing after college." It may also be that they perceive themselves to be judged by how much code they can sling, and not the quality of their writing. And in a large enough department, the work that depends on math ends up being given to the one or two "math people." I'm one of those.

But I suspect that there's a relationship: If their writing is hard to read, their code will be hard to read.
