People who aren't poets find a variety of uses for poetry. The top selling book of American poetry at amazon, children's books aside, is Howl at 3,227 (Sales Ranking). Ariel is quite high at 4,007. What Narcissism Means to Me stands at 5,355, suggesting that the post O'Hara urban sensibility is still appealing. And let's not forget Alicia Keys and Tupac. A certain number of people will buy a book by whoever's poet laureate at the moment. And the immortal Mattie Stepanek, wise beyond his years, ranks up there with Richard Wilbur.
