Modified my “Share on Mastodon” mu-plugin, i.e., where I keep my PHP filters/tweaks, to correctly “thread” cross-posted replies to not only notes, but articles as well. https://indieweb.social/@janboddez/109884956066372057
Should probably share the exact code, but it looks something like https://jan.boddez.net/wordpress/share-on-mastodon#threaded_toots, i.e., I’m using a regex to look up the note or article I’m replying to and then fetch its syndication URL, which I use to derive and set an `in_reply_to_id` parameter.
