Part of the promise of #ActivityPub and the #Fediverse is that you can interact not just with different servers, but different kinds of servers. I’ve been testing how well different platforms interact, reported some bugs, and even fixed a couple of them.
Not surprisingly, I’ve found that the bigger projects have good #interoperability with each other, smaller projects have good interoperability with Mastodon, and smaller projects are more likely to have bugs in interoperability with each other. Sometimes you can view someone’s posts or profiles on another platform, but following them doesn’t work, and replies don’t make it back. Or only some kinds of posts are visible.
Does anyone have a #compatibility matrix I can contribute to, or should I just post my notes somewhere? @fediversenews
