Overall I like this advice. However some of their examples do not really push the point. In the first example they make the text both bigger _and_ bolder and smaller _and lighter. This is good, however it is contrary to what they say. In the shadows example, I prefer the bordered version. Shadows do not always look good and borders are "safer" to use.
