Since I don’t have any concrete sense of a “poetry community,” I write toward our craft’s improvement. Poetry has devolved into confessional prose with line breaks because it is often taught as an emotional unlocking mechanism, especially when poets walk into troubled institutional settings as pseudo-saviors.
As you say, poetry is the use of words, images, rhymes, rhythms and other literary devices in the creation of art in which the order of these devices is paramount. Too many people start writing poetry without reading great poetry, especially aloud. Most people who start writing poetry today are not systematically taken through poetic verse forms and meters. So, they write as obliquely and dryly as they speak, one sentence fragment and cliché after another.
If we consider how many thousands of poems have been written on the same few subjects, we realize that the literal situations are like blank canvases upon which we paint with words. At the risk of this blind bard taking the painting metaphor too far beyond abstraction, most poetry today sounds like a canvas painted with clear paint, guiding the eye back to the canvas itself rather than to a brilliant painting upon it.
