The best way to celebrate it is to BUY a collection of poetry, READ it, LOVE it, and POST a review on Amazon! Then post that review on Facebook! Poets are singularly noble creatures, filled with not just a passion for words and emotions, but with integrity, because most of them have accepted that they will never be famous. They write because they can't NOT write, and let's face it, the world needs as much poetry as possible right now. Celebrate!
I have a pile of books I've bought from poet friends, and will try to read them all and post one review a week.
April is the Poetry-ist Month of all -- yes!
