Over in #WordPress news, we shipped in Jetpack our Social Sharing feature for Mastodon.
This will allow site owners to link to their Mastodon profile and automatically (or schedule) shares of their blog posts to their fediverse followers.
Automattic is both doing this and working on ActivityPub support for WordPress as two side of the coin. Whether or want your site to natively be on the fediverse or share to other profiles, we want you to do both.
