I love experimenting with white space in poetry. There is so much potential for unique things. Many poems try this kind of experimentation, but sadly they never get much attention, so the default remains to do things the standard way. It's too bad Hive (still) doesn't support CSS so we can't do advanced formatting play. But then again, that would be a lot of work to do even if it was supported.
Anyway, I love your experiments here! Keep it up.
I also get inspiration for poems while consuming other media. I usually keep some index cards in my pocket, in fact, to write down random scraps of poetry. I think those raw inspired moments make the best poetry. That is, in fact, what Bashō advised for writing haiku.
I do my writing on Google docs so it is always open on my phone. As I see a movie or listen to a song, I write on the Google doc editor.
It would be cool to be able to edit poems further. Maybe one day, we will have that function.
