Mastodon

Mastodon is a federated, ActivityPub-based social network made up of thousands of independently run instances rather than one central server, popular among developers, open-source communities, and privacy-conscious users who left more centralized platforms. Articles under this tag cover how to auto-post an RSS feed to Mastodon, how its per-instance API and hashtag-driven, algorithm-free discovery model works, and how it compares to other alternative platforms like Bluesky and Threads for automated content distribution. Mastodon is a supported PostRSS destination on every plan, including Free, connected to whichever instance your account lives on. Much of the material here is community-shaped, such as makerspaces and hackerspaces, because those are the groups that adopted the network first. There is also coverage of Ghost's native ActivityPub support, which changes what you need a separate tool for, and a side-by-side comparison with Bluesky and Threads for feed-driven posting.
