I thought I wanted to customize the layout of my document a little bit, so I started looking at the various styles that are available.
Then I came upon the memoir package (which is supposed to help with these things); the 550 page manual that comes with it has so effectively scared the crap out of me that I’m now looking at my crappy looking document and thinking: “heck, it looks good enough”.
I will gladly leave typography to the typographers.
