When posting in #WordPress, its always a good idea to include a title. Even if the main purpose of the post is to communicate over the #Fediverse, not having a title messes up the WP blog experience. The theme will probably have a big say in how it turns out, but nevertheless, if you change themes at some point you’ll be glad you used titles.
By the way, this post includes an image an alt-text. Looking forward to seeing how it carries over to the Fediverse from WordPress.
