There is something essential and necessary about the immediacy and democracy of poetry. If you look at the history of literature, poetry is the one enduring genre from Homer to Ashbery - no other literary form has lasted as long. The novel is only two or three hundred years old... And yes, it's mainstream if we look back, we often turn to poetry to encapsulate what was going on in a particular moment because it crystalizes the experience in a very condensed and meaningful way.
