Thanks for the A2A Jeff. I’ve only brushed up against this topic, but here are my impressions:

• Enough relaxation of postmodern skepticism (or perhaps an application of postmodern skepticism to postmodernism itself) to allow for optimism.
• A tentative reintegration of the ideals, expressions and attitudes that postmodernism rejected, while retaining self-awareness about this process (for example: conscious naiveté).
• A form of syncretic integralism.
• A natural cultural maturation process beyond rebellious black-and-white formulations of adolescence into the nuanced gray areas of adulthood.

In my own work, I view the post-postmodern or metamodern stance as applying conceptions of multidialectical synthesis to the cultural-artistic sphere.

My 2 cents.
