I ran across ProseMirror yesterday and my first thought was: I want this for writing and posting to my website! Not having the time or experience to set it up and integrate it myself, I wonder if there’s a public instance of it on the web that has Micropub integration?

That would allow it to publish to to several dozen different CMSes including WordPress, Drupal, WithKnown, Craft, Jekyll, Kirby, Hugo, and Micro​.Blog among a growing set of others.

I know that iA Writer recently added Micropub support to allow people to use their tool to publish this way. Sadly they’ve only got it working as Mac/iOS clients and not as a web client, which is something at which ProseMirror might excel.
