I don't know that I had a sense that there was such a thing as "the poetry world" in the 1960s and early 70s. Maybe poets did, but for me as an onlooker and reader of poetry, poetry felt like it was part of a larger literary world. I mean, even the phrase "the poetry world" reflects a sort of balkanization of American literary and artistic life that has to some extent happened since then.
