As you might have read on my meta page, I inteded to remove support for ActivityPub:
I am considering removing the ActivityPub support from my website. Right now, my website is able to provide posts formatted as ActivityPub entries; post to my followers when I write new content; and receive comments via ActivityPub.
What bothers me is that the logic is a bit flaky and it fails quite often. Besides, I only have 2 followers and one of them is a testing account of mine. Removing it would cleanup the code and possibly not hurt anyone.
I just did it for the reasons mentions above. It’s a bit sad, but it gives me some peace of mind nevertheless. Maybe in the future, there will be a more straightforward protocol that is more massively adopted that I can implement. For now, I don’t see the use for this website.
Or if you don't know what a response is, you can always write a webmention comment (you don't need to know what that is).
