After teasing support for the fediverse earlier this year, the newsletter platform and Substack rival Ghost has finally delivered. “Over the past few days, Ghost says it has achieved two major milestones in its move to become a federated service,” reports TechCrunch. “Of note, it has federated its own newsletter, making it the first federated Ghost instance on the internet.”

From the report:

Users can follow the newsletter through their preferred federated app at @[email protected], though the company warns there will be bugs and issues as it continues to work on the platform’s integration with ActivityPub, the protocol that powers Mastodon and other federated apps. “Having multiple Ghost instances in production successfully running ActivityPub is a huge milestone for us because it means that for the first time, we’re interacting with the wider fediverse. Not just theoretical local implementations and tests, but the real world wide social web,” the company shared in its announcement of the news.

In addition, Ghost’s ActivityPub GitHub repository is now fully open source. That means those interested in tracking Ghost’s progress toward federation can follow its code changes in real time, and anyone else can learn from, modify, distribute or contribute to its work. Developers who want to collaborate with Ghost are also being invited to get involved following this move. By offering a federated version of the newsletter, readers will have more choices on how they want to subscribe. That is, instead of only being able to follow the newsletter via email or the web, they also can track it using RSS or ActivityPub-powered apps, like Mastodon and others. Ghost said it will also develop a way for sites with paid subscribers to manage access via ActivityPub, but that functionality hasn’t yet rolled out with this initial test.
