The ActivityPub protocol, best known as a key element of Mastodon, is catching on for multiple uses. There’s an ActivityPub plugin for WordPress, which makes a site’s feed available through ActivityPub. When you add it to your site, people with Mastodon accounts can use them to read your blog. (Some Mastodon sites put limitations on reading long posts.)

The current version is in beta and has limitations. The WordPress site has to be in your root directory. Because of the way I set this site up a long time ago, that locks me out. But recently Automattic, the company behind WordPress.com, has taken over development of the plugin. The result should be faster development and fewer limitations. Matthias Pfefferle, the plugin’s developer, will continue to work on it (and hopefully get better paid for it).
