One of the really cool things you can do with the ActivityPub plugin is select how content is federated.
My last post only had the title, some images and a link, previously I was federating the entire post (let me know which you prefer by replying to this post from your fediverse instance).
This post I hope will provide the title, an excerpt of 499 characters (if this post has more it should truncate), and a short link at the bottom.
Previous shortlinks have not been clickable, I hope the link that accompanies this post is. If not I may end up playing with the settings to see how I may include one. Unfortunately this is a setting that is set prior to posting and only reveals itself once I have received the post via my identity on my Pleroma instance.
Fingers crossed I get it right first time!
