I wish someone would point out to Dave Winer that because micro.blog uses Micropub, one can use a number of different editors, perhaps even one of their choice like the the Ulysses that his correspondent is using, to publish their writing to their blog. I personally use Drafts on my iPad and Omnibear whereever I use Chrome to write my blog posts.
Someday I want to work with writing some Javascript to post to my blog and see if I could get that to work with Roam to publish a block of text via Micropub.
