I can't believe I missed this announcement. This is great to see!

Enter the fediverse with ActivityPub, broadcasting your blog to a wider audience! Attract followers, deliver updates, and receive comments from a diverse user base of ActivityPub-compliant platforms.

With the ActivityPub plugin installed, your WordPress blog itself function as a federated profile, along with profiles for each author. For instance, if your website is example.com, then the blog-wide profile can be found at @example.com@example.com, and authors like Jane and Bob would have their individual profiles at @jane@example.com and @bobz@example.com, respectively.
