You are making some solid points here, Andy Meyer, and I agree with a lot of what you have said.
Your 4th point is really something I’d like to learn more about because I often feel like my poetry is still stuck in the stone age. One fear I had before creating Poetry in Form was that it would seem too old-fashioned or rigid for the Medium audience which seems to largely prefer free verse. I decided to go ahead with it anyway by challenging readers and writers to forget everything they knew about poetic form and give it a chance, just be open to it. The response I received/continue to receive is amazing. My hope is that it will continue to grow and influence the poetry “scene” on Medium in a positive way by showing how powerful the use of poetic form can be — both for the poem and the poet.
By the way, I enjoyed your sestina. I like that it challenged the idea I have in my head of what a traditional sestina should look like. This is a perfect example of what I mean when I say “forget what you know about poetic form” and it is a great example of how traditional forms can be still used to illustrate modern ideas.
