I’m not sure there is a distinction between what little flarf I write and my poetry-poetry. Maybe in the method. Most of my flarf is entirely google-generated. My poetry-poetry comes from all kinds of sources as well as whatever can be said to be “my” voice(s). The final effect, however, is not all that different.
I don’t write much Flarf these days. No time. Kasey and Michael and Rodney and Drew turn out such amazing stuff that I don’t need to. IMHO, it’s good poetry. I mean actually good poetry.
Bad flarf is stilted or tries too hard or just isn’t funny. It’s also bad when it oversteps the invisible boundary that is outside of the visible boundary that one must overstep in order to write flarf in the first place. What I mean is, for example, the injunction against the n-word still holds. For me anyway.
