I enjoyed the essay very much--and I am glad all sorts of hybrids are being discussed in the New York Times. But, hey, folks: this genre isn't new. There have been writers and readers preferring it for decades--because it solves a conundrum.
A personal example: When I published my second memoir in 1997, I debated its genre. The book was a combination of my stories of loss and change, and good advice I'd received over the decade I went through cancer, bankruptcy, divorce, marriage, and other such upheavals.
