I've been reading a lot of nonfiction lately in an effort to feel like an adult and get edumacated.
I've run into a several books now where the designer/whoever does the layout puts part of the text in a call-out box to call attention to it. I find it aggrivating. I understand that someone thinks the sentence is important and all, but since it's not a new idea - it's in the main body of the text - it just looks like the publisher is bulking up the page count. I promise, I'm a growned up person and can figure out the important bits myself. It's not just parenting books, which are written for idiots*. I've found this in business development books, too.
Oh, and Ms. Big Margins, you haven't written a text book. Save a tree and cut back on the white space.
On the other side of things, I really liked and recommend wholeheartedly,
Rethinking Thin by Gina Kolata. It looks at the history of dieting and the current science about the biology that thwarts dieting. It's well researched and written.
