Never heard post-postmodernism used before. I regard postmodernism as anti-rationalist, anti-ontological, schizo, discursive, nihilistic, cultural relativistic, identity confused. Lyotard wrote a little piece on it, but I haven't read it yet. Of course it is a vague term that gets thrown around alot, and so it has some overlap with postcolonialism, deconstruction, poststructuralism, etc.
