The UI part that often bogs down the posting process is the complexity of Gutenberg or the myriad of meta-boxes. To remedy this I try to pair one of the many Micropub clients (I like Quill or Omnibear as flexible examples) for posting to my website and then allowing Post Kinds to handle the rest for creating reply contexts and posting the minimum necessary metadata.
I think Post Formats didn’t go far enough. I love Post Kinds Plugin for extending the idea, particularly into some of the UI one sees in the social space. It also has extensibility to allow new formats as well as customize-able display, so if you want an annotation display or a “chicken feed” (just to demonstrate the point) on your site, a few modifications and you’re off to the races.
