Bokeh has its uses, mostly artistic. The problem is, most people use it as a crutch for shallow DOF, to seem more artistic, or because they are often pretentious.

Bokeh properly applied can add to an image, after all part of it is the shape, and texture thereby given, of your aperture, and how it relates to your image, not just the lack of focus. People forget the esthetics of it.

Usually, though, it really is used to hide poor focusing.
