I could easily assert that so many pwoermds are being written these days merely because I have promoted the form. I have not invented it. The inventor is unknown for sure. It may have been Cor van den Heuvel, working in the realm of haiku, or it may have been Aram Saroyan when he was a minimalist concrete poet. Or it may have been someone who preceded both of them.
Regardless, the pwoermd is flourishing, and each year (for five years now) I've hosted an event event (International Pwoermd Writing Month) to serve as a lo-res response to Poetry Month and National Poetry Writing Month. So far this time, we have fifteen known participants (counting myself), who are posting work at sixteen different sites on the Internet. These people live in at least six different countries on two continents, and they'll be working in at least five languages (I'm counting Scots here).
To celebrate this year, I'll create a pwoermd each day (no idea for one yet today), and I'll post occasional pieces about pwoermds.
The participants as they stand:
