I think all writing is about writing. All writing is a way of going out and exploring the world, of examining the way we live, and therefore any words you put down on the page about life will, at some level, also be words about words. It's still amazing, though, how many poems can be read as being analogous to the act of writing a poem. "Go to hell, go into detail, go for the throat" is certainly about writing, but it's also hopefully about a way of living.
