To sell last-minute custom poems to HN? Impressive cynicism. Submarine poetry competition might be fun, but the quote is not even from the article. I saw it by randomly clicking on substack, then couldn't even find it again to link here, due to substack's inscrutable layout.
Now that you've brought up the topic, how should one sell poems? Maybe start earlier with content marketing and link the product somewhere in the content? Apparently this blog has only been submitted twice to HN, today and three days ago, with zero mention of poetry. But it does mention weddings.
Most poets who make any money sell their work by publishing it as song lyrics, I think. I don’t think we have many rock star poets left, and I’d be surprised if many at all made a living at it.
I’ve most often bought poems from people sitting on the sidewalk writing them out, FWIW :)
