"Also, if you know you're writing for a politically correct professor or scorer then it is best to play to your audience, get your grade, and critique the bastards to the heavens AFTER you get your diploma."
This is very good advice for business writing in general.
I agree. One of the first things I recall in any writing class was to know, and understand your audience. The ability to either bring them to the point of understanding on your level, or reach them at theirs, is based on this.
