@stefan Hey, as far as I understood the Activitypub plugin for Wordpress: it really change your website into in own instance (eg. each time you publish, the blog-post is also a Fediverse post, and replies are built-in, etc...).
My script is much more humble, it only displays the replies to an existing post on the Fediverse. So, it certainly require more work. But I'm sure it will be easy to transform it into a Wp plugin. 1/2
@stefan The most difficult part will probably be to add a new 'text field' to the admin panel of the Wordpress CMS. This is where the user can enter the MastodonURLID of the article.
