K.C. Bacon turned me on to this Joseph Epstein essay from the Wall Street Journal. I agree with it in the main, though I could quibble about a few of Epstein's lesser points.
The author's thesis is strong, if obvious to those of us in the writing trade. Few people care about poetry outside of academia.
Bacon reminded me of another Epstein essay that I read years ago, which covered a lot of the above material in more depth.
"Who Killed Poetry" is actually the better read if you have a little time to digest it.
