The signs of the coming apocalypse are many, but none are starker than this Web headline in the April issue of O: The Oprah Magazine: “Spring Fashion Modeled by Rising Young Poets.” Yes. Spring fashion. Modeled. By rising young poets. There follows a photomontage of attractive younger women — some of whom are rising poets mostly in the “I get up in the morning” sense, but all of whom certainly look poetic — in outfits costing from $472 to $5,003. This is all part of O’s special issue celebrating National Poetry Month, edited by the noted verse aficionado Maria Shriver and including interviews with “all-star readers” like Bono, Ashton Kutcher, the gossip columnist Liz Smith and someone named James Franco, who is apparently an actor.
