In March, WordPress.com owner Automattic made a commitment to the fediverse -- the decentralized social networks that include the Twitter rival Mastodon and others -- with the acquisition of an ActivityPub plug-in that allows WordPress blogs to reach readers on other federated platforms. Now, the company is announcing ActivityPub 1.0.0 for WordPress has been released allowing WordPress blogs to be followed by others on apps like Mastodon and others in the fediverse and then receive replies back as comments on their own sites.
