Yes, it’s true! It’s been publicly stated that haiku is a true poetry form. Ron Silliman was in Ottawa and in the middle of his workshop, began to talk about haiku as if it was, well, you know. If you go to his blog, (just google Silliman’s blog) there is a discussion of haiku in which he cites Jim Kacian, John Martone (specifically John’s wonderbook, Kasana) and others, and talks about haiku in a terrifically accessible manner. Go there for a treat!
