OK here's my take....
Everyone has different taste.
There is no good taste or bad taste, there is just different taste.
Taking my work to a craft show, maybe 1 in 50 might come into my booth.
I can safely assume, they don't like what I like.
Of those who come in maybe 1 in 10 might actually buy something. The others liked my style, but I just didn't have an image they liked enough to buy.
So, to complete a sale, I need probably 500 people to be at the craft show. That will be people who like what I shoot the way I shoot it. Now I could flatter myself and say they have good taste. But that's not it. They have my taste.
But, if I can sell an image to 1 in 500 people, some of the shows around here almost guarantee you 20,000 people in a weekend. If I go to one of those shows, I'm practically guaranteed 40 sales, and one of my fellow photographers says, if you go to that show, it will pay for your business. At least it pays for his.
So I only need 1/500 people to have "good taste" to make a decent living. And really, who cares if there's a pile with bad taste, as long as they don't feel obligated to hang around my booth, so those with "good taste" can't get in.
