Brian Brodeur's How a Poem Happens recently had an enlightening Q&A with poet David Huddle, a part of which I'll paste below. This entry, and the whole blog is worth a long look.
Do you have any particular audience in mind when you write, an ideal reader?
Tough question. I used to claim I thought about audience only after I had finished the piece of writing and had begun to wonder where I should send it. In recent years, however, I’ve been writing with my students, and in that case I’m writing for the immediate audience of the writing class where I will present my poem alongside the other poets presenting theirs. I do still like to think that I don’t write “to” any particular audience. This is sort of like confessing that one is somewhat promiscuous but one is not a complete slut.I'm not familiar with Huddle's poetry, but I will be pretty soon, you can bet, based on the quoted poem in that entry.
