I agree with mfunnell in that the question could mean a couple different things.
In the sense of, do I like (or like to create) images with prominent use of out-of-focus areas, it depends on the image. Catchy? Yes. Easy to use? Yes. Easy to use in a appropriately and with strong vision, is more difficult and less-seldom seen. Shallow DOF does seem to have been a bit of a fad for awhile with the resurgence in 135-format cameras and lenses and the sudden mass availability of inexpensive medium format to hobbyists, but that doesn't mean I don't enjoy the technique when it's well-used.
In my own photography I certainly use it when appropriate to help subject isolation; either with large lens aperture or tilt/swing movements (and of course the selective focus thing is a whole discussion 😛 ). At least 2/3rds of my images use deep DOF, but I like using shallow focus with close-up and some medium-distance photos. When I shot with Fuji 6x9, I used a shallow depth of field in most of my images as the larger format allowed a more subtle look. Certain images are absolutely improved with shallow DOF, some not. Depends on the subject and elements in the scene, and geometric/color composition used by the photographer.
As for, do I think the discussion of and experimentation with the character of the out-of-focus areas (what I usually think of when I hear "bokeh"), I think that too is something that can maybe be faddish but I personally find it interesting. As something that can strongly affect the look of an image I believe the look of OOF areas is certainly worth discussing! I also think it's perfectly fine that some/many photographers couldn't care less about the discussion, or don't have a preference in the "look" that different lenses provide in that sense.
To each their own! Art, by it's definition is largely subjective 😀
