Thanks for this explanation.
I loved your short form example about the rat. Well-written and thought-provoking.
I've been doing more quasi-short form posts (mine always wind up over 150 words; have to work on that) because that's all I'm choosing to devote time to. I'm not trying to earn a living on Medium, so it made sense for me, and I'm happy to see it acceptable as a legitimate form of writing here.
