I don't think the arrival of one discourse displaces another. I don't see this as an either/or. I think new discourses, such as Flarf, enrich discourse, even if by making one more in love with what one was already in love with. Maybe in love in a more complicated way. Bring it on. Here's how the piece in the Star ends:
Toronto's poet laureate, Dionne Brand, says poets from every period have used the material of the day, from "cave walls to digital walls."
"Whether one mines daily life or physical texts or digital texts, one still has to choose," Brand wrote in an email. "The choices are interesting, or not, and whether they are interesting is what makes the poem."
