John, with all due respect, your website was put together by Damaris West: a semi-disabled elderly lady with a disabled husband, who self-published a novelette called Skolkham: A tale of good and evil magic, and who has a main website which is mainly about the Tuscan property market, breeding dogs, and cookery.
Chris, she also has a keen interest in poetry and has presumably posted this description based on understandings reached through reading and participation in the world of poetry. I don't see how any of the attributes you mention make her non-credible.
For me, her description is a concise articulation of views that prompted me to start this thread and whose origins and development I'm trying to understand in terms of factual history.
Thanks for that link and the comments. Yes, there is a wide spectrum of views out there. Nevertheless, among poetry that is published today, free verse is hugely predominant.
