Unless I have managed to mess up something really bad, this Blog should now be a part of the Fediverse and all posts here should get published to the Fediverse automatically. If all is well, then searching for @suramya@suramya.com on a Mastodon instance should allow you to add me there and all posts (with their full text) made here should get published there automatically.
Once the ActivityPub plugin is installed, each author’s page on your WordPress blog will become its own federated instance. In other words, if you have two authors, Jane and Bob, on your website, example.com, then your authors would have their own author pages at example.com/author/jane and example.com/author/bob. Each of those author pages would now be available to Mastodon users (and all other federated platform users) as a profile that can be followed. Let’s break that down further. Let’s say you have a friend on Mastodon who tells you to follow them and they give you their profile name @janelivesheresomeofthetime. You search for her name, see her profile, and click the follow button, right? From then on, everything Jane posts on her profile shows up in your Home feed. Okay, similarly, now that Jane has installed the ActivityPub plugin on her example.com site, her friends can also follow her on Mastodon by searching for @jane@example.com and clicking the Follow button on that profile.
