Pursuant to my commentary about navigating the long tail, Ryan Shaw of Berkeley's SIMS program pointed me towards a term, semionaut, coined by artist Nicolas Bourriaud. One of Bourriaud's claims to fame is the late 90's text, "Relational Aesthetics," where semionaut came from. Emerging from the art world, "Relational Aesthetics" is probably over my head, but I'm game to dig up a copy and see if I can get the full import of Bourriaud's commentary.
Interestingly, it's difficult to find a review or two of the book, despite what appears to be some fairly broad impact. An in-depth review in the London Review of Books, by Princeton professor Hal Foster, is behind a pay wall.
"Postproduction" also looks interesting.
Thanks Ryan!
