This is a public post with no title and no featured image. When I posted privately, it uses the word PRIVATE: in front of the non-existent title. I am expecting that this will display with no title. The one thing I do not like about using no title is when I view the posts page, I have no way to identify the post because they just say Untitled.
I have also been categorizing these posts as social, but I think I might change that as I am not inviting comments.
