I’ve now removed the titles in the RSS feed from posts in the micro category using the_title_rss. So I’ve reenabled adding of titles through wp_insert_post_data. If this works this post will have a title in my dashboard, but all get through to micro.blog
You are completely right Chris, I am probably digging a hole for myself that I’ll regret later. Without the time and skills to dive deeply into the indieweb I get that feeling all the time. Having some fun though.
