"In addition to the way servers communicate with each other across the Fediverse, #ActivityPub also defines a “Client-to-Server” API.
This #API is mainly designed to allow apps and clients (such as mobile apps) to publish content to a Fediverse server.
In the future, this could open up interesting possibilities for #WordPress — for example, allowing WordPress to act as a bridge or proxy, making it easier to bring in and federate content from other tools or platforms."
