When I was creating the Underground Literary Alliance, I threw away the idea of a "better mousetrap" as far as the art itself went. I saw that writers thought all they had to do is write, and the world would find them. Editors and readers would "beat a path" to their door. The notion is clearly false.
I've come around to an extent, however. I now realize that, while promotion is all, you still need, in this hypercompetitive society, a better product. I'll have a few more words about that coming up.
