Poets in the academy have been, for the most part, blissfully (or tragically, depending on your perspective) separated from the part of the English Department that does literary theory. Derrida rarely comes up in the MFA workshop. There has traditionally been a clearcut division of labor here. Now there are poets who actually have serious scholarly heft, like John Hollander, but that is more the exception. What Charles Bernstein did with the poetics program in Buffalo was to bring theory and poetry together in an academic setting, where this had not been done before.

Most literary humanists are not poststructuralists anymore, if ever they were. Most I would define as methodological eclectics specializing in a particular area or period, and the further you get away from elite institutions, the less likely you are to find a predominance of theory.

True deconstructionists are extremely rare nowadays. I can't think of any in Kansas, for example.
