From Matt Mullenweg’s talk at WordCamp Canada:
Day One is a fully encrypted synchronized blogging and journaling app, that runs on every device and the web, and you can have shared journals with others. It’s the first place I go to draft an idea, or for example, to write this talk.
This was a little surprising to me. In a way, it matches the workflow I sometimes use in Micro.blog. I use our private, encrypted notes feature to jot down ideas or write a draft, then move it into a blog post. But most of the time I just start right with a draft post.
