Well because of the shallowness of the depth of field you’re going to get bokeh no matter where your focus is. The one of the glitter pile really confused me as an observer because the focus was in a narrow band in the middle of the picture, I wasn’t sure where you were going with that. I’m by no means an expert in macro photography but if I can use my flower from this week as an example: http://www.flickr.com/photos/kestrana/4994382241/
You can see the water droplets just to the right of the center are already blurry and I actually cropped about 25 pica along the right hand because it was blurry and distracting from the in focus subject of the water droplets and stamen.
True also of my stuff, as in this example:

The leaf is less than an inch in diameter and only gently cupped, but the edges still blur.
Personally, I like the bokeh evident in macro shots. It creates a challenge in composition that I really enjoy.
