Ming has a new post up, continuing his investigation. This one is just wrong.
He is falling in to the "well it's all just subjective" trap, and is either saying outright or implying broadly that one cannot after all have universal reach. His little graphic strongly suggests that you can only have so much reach, which you can spread thinly to lightly connect with a broad audience, or concentrate to strongly reach a small one.
This is a cop-out, an excuse. It is manifestly clear that one can intensely reach a large audience, there is lots and lots of Art of various media that does just that. Not, perhaps, universal, there still remain cultural differences that matter. But broad and intense.
It is possibly to connect broadly and intensely. It is very difficult, but that is the star you should steer by, not some half-assed "it's all subjective" streetlight.
Paradoxically, this is accomplished by looking inward. I believe, I think, that the most powerful work is executed when the Artist brings the world within, and then in that tiny inward, but somehow complete, universe, works selfishly and alone.
This is why the Artist so often consumes art voraciously and lives widely, it is to bring that world inwards, so that the selfish, narcissistic process of Art-Making can then connect with the wide world.
