I collect newspaper poetry of maybe 1776 to 1830. It was always there. And my memory of reading papers in the 1950s was that there was always poetry in those papers, as well. My father and mother met over his poetry column in the college paper in the 1920s. Perhaps today the young write rap poetry. That only the young will read.
When I was in school, we always were read poetry. Children naturally like rhyme and rhythm and learning poetry is fun. Good for memory and brain training.
I wonder if schools still teach poetry.
