Here's a good mvp article for a Microsoft MVP or aspiring one to write. In  
fact, I nominate Jezebel.

Users make a lot of mistakes in setting up styles. They use Normal as a  
variable base style; they fail to use Word's ready-made heading styles;  
they fail to incorporate their list numbering into styles, etc. Take all  
of these common errors and address the situation of the user who has many  
styles in place that are in these ways unsound. What is the most efficient  
way for the user to make his or her system of styles rational and proper,  
starting not from the artificial position of the user totally innocent of  
styles but from the user who has applied styles inconsistently and  
incorrectly.
