Thanks for the link, Medievalist. I checked it out. It sounds like they're echoing a feeling that I think the majority of us have, that being of too much labeling, pigeon-holing, and categorizing art/written work into one particular genre/category or another. It seems we've lost the old idea of just plain general fiction.
I personally don't think this interstitial movement is going to solve the basic problem because the resolution needs to come from the other end - the market, but more than from the general market, it needs to come from the publishing houses and agents who have created this genre tied period in creativity.
