Michael,
I struggle with this all the time and especially in conversations with strangers, I assume folk are open to broader ideas when they are not and everyone is upset! But perhaps one key to broadening a topic is correct timing.
I, myself like looking at the "suggestions and uncertainty" inherent in many images made by gestures, and scantily detailed images, as these force us to "fill in the blanks" from our vast intellectual resources of analogy, memory and imagination.
Nicolas, on the other hand has rewound your movie and asked, Michael, are you in fact correct in saying "resolution isn't everything". The thread had, indeed, developed in a focused way around the beauty of a certain vagueness, as then we are encouraged to complete the drawing.
I am not sure if I have it correct, but I imagine that, had Nicolas jumped in at post # 2 and declared that details were important, (as when one returns home, detail cannot be created, but one can always throw away unwanted detail purposely by careful and selective blurring), then he would have provided an interesting opposition to your celebration of having vagueries from the outset.
In my own experience, however, I have not found it satisfying to blur afterwards, although, technically, I can craft an image to appear as if taken OOF and with slow shutter speed.
My best work has been in following a person at a museum and taking photographs as we both moved. But it is difficult as the museum staff call this "harassment"!
