@daveymoloney’s microblog status page is most likely done by his having a page and menu link that displays the WordPress Post Format type “status” posts. (Incidentally you already have that page on your site, you just need to put it in a menu somewhere: http://willtmonroe.com/type/status/) I’d suspect that he took the RSS feed from that page and piped it into Micro.blog as well. Since you’re using Post Kinds plugin, you can do something similar using a URL format like https://boffosocko.com/kind/note,photo,like,listen/ or for porting to micro.blog using a similar feed URL like https://boffosocko.com/kind/note,photo,like,listen/feed/. You’d just need to put the names of the types you want to use/have in the list separated with commas.
Let me know if you need more help!
