I wrote the previous post in Obsidian and used the micro.publish plugin to publish it to this site, however the graphic on the post was not uploaded. I had to manually upload the graphic and then insert the link to it in the post article here on micro.blog as a post publication step.
Also note that the cross posts, particularly to Day One, do not include the edit, which is a problem with cross posting from site to another. In my experience only the first version of a post is every cross posted no matter the source and destinations.
