I write many of my blog posts on this site using the Drafts app on my iPad, and I can do that because micro.blog supports an open API that provides the ability to integrate any editor to it. In this manner micro.blog is the most open platform that I have used. In fact that means I can even use Drummer to write and publish a post to this site. The irony is, I cannot do the reverse as there is no way for me to write a post in Drafts to be published to my Daynotes. The cause in my opinion is that Dave is focused on a file format rather than an API.
