This is a short article just to see how well the new integration works, but on October 11 2023 WordPress announced that all blogs they host can now be followed by users of Mastodon and other Federated systems.
At first I thought they were going to limit this for just the Business tier (the one you can add plugins to) but they’ve made it available to all tiers.
It’s not enabled by default but to enable all you need to do is go into Settings -> Discussion and you now see a new Fediverse settings section:
Just enable the Enter the fediverse slider and you are given your blog’s address in the fediverse.
For me, in Mastodon I just entered the given address into the search box,@area-51.blog@area-51.blog in my case and it showed up almost immediately. Click Follow and I was then following my blog.
Self hosting
I did check afterwards and for those who self-host WordPress the plugin is available at https://wordpress.org/plugins/activitypub/
