Grumble. Why do people spend so much time and energy on making documents or presentations look good when they are not competent to do so? Just stick to the style guide and spend the time and energy making sure the content is accurate and the form appropriate.
(In the 80s I worked with many very smart people who needed help getting their content out of overly formatted hell. I find it despairing that every generation has to repeat the same information delivery problems of the past.)
