[$] Microblogging with ActivityPub

As of late, concerns about the future of Twitter have caused many of itsusers to seek alternatives. Amid this upheaval, an open-sourcemicroblogging service called Mastodon has received a great deal ofattention. Mastodon is not reliant on any single company or centralauthority to run its servers; anyone can run their own. Servers communicatewith each other, allowing people on different servers to send each othermessages and follow each other's posts. Mastodon doesn't just talk toitself, though; it can exchange messages with anything that speaks the ActivityPub protocol.There are many such implementations, so someone who wants to deploy their ownmicroblogging service enjoys a variety of choices.
