Huh?

Reginald Shepherd blogs over at the poetry foundation site. Here is a post of his concerning "post-avant" poetry with the 100+ comments that follow. Now, I admit to being pretty slow on the uptake, but why do poets care so much about what "school" of poetry they are lumped into? I can understand poetry scholars arguing over these things in the future, but if you are writing poetry and you are worried about what that poetry is called then you should take up a new hobby.
