I found the most confusing, or unintuitive, thing is how to create a new post.
Eventually, I figured out that the following link will create a new post:
https://write.as/# Or when logged in at the main page of a blog, the ‘Menu’ in the upper-left corner has as it’s first item ‘write.as’ which if clicked starts a new post. Also I now see that clicking 'write.as in the footer will start a new post. You could also go your Blogs page and there a ‘New Post’ link there. If not logged in,
https://write.as starts a new post (that how I figured out that link will create a new post).
But if you’re viewing a blog post, I don’t see any link that starts a new post other than (unintuitively) clicking 'write.as in the footer, or the extra step of returning to the Blogs list to see the ‘New Posts’ link there.
