In this tutorial, we will build a small microblog that implements the ActivityPub protocol, similar to Mastodon or Misskey, using Fedify, an ActivityPub server framework.
I’ve never quite understood the appeal of ActivityPub.
Looking at the list of goals in the article, the only benefit in addition to what can easily be done with RSS is knowing who follows me. Maybe it’s just me, but if I’m writing to a blog or a microblog I just don’t really care who follows me or even who reads it.
There are more social features built into ActivityPub, likes and shares for example, but at that point I’m likely not running my own server and am trusting a third party to do it for me. The idea that there are multiple hosts I can choose to trust rather than one centralized one feels more like a principled argument than one based on real benefits of, for example, owning my own content or censorship resistance.
