You continue to make the assertion that shallow DoF makes a photo interesting, that's where the dog turd photo comes into play, it's just an example of something that proves shallow DoF does not just make a photo interesting. I'm done discussing the topic really, if you believe that shallow DoF makes a photo, more power to you.
I'm not sure why you keep beating down on this straw man, but I'll say it one last time. Shallow DoF is a stylistic effect that can work well for some subjects. It does not work for all subjects, and insufficient DoF can ruin certain other subjects.
The mere availability of this stylistic feature doesn't mean you must use it for all images henceforth. Can you agree with that?
