I see. I haven't particularly felt constrained by any rules in writing my novel or my poems, but I suppose creating an entirely new format is a good way to suggest from the start that the are no rules at all.
"More like a poem, but an entire story" makes me think of epic poems from history, like Homer's Iliad and Odyssey, but I suppose it's better not to make that association since that comes with something of a definition of its own.
In any case, good luck! If I post any writing that I think fits well as a "micro-novel," I'll use that tag myself.
Thanks! And likewise, I haven't felt particularly restrained either, just kind of a fun way to categorize tiny stories in my mind I guess...like I said, it should just become whatever fits for people, writers and readers alike.
Thanks for the comments and thoughts! Always nice to meet another poet.
Namaste
John
