Tumblr will add support for ActivityPub, the open, decentralized social networking protocol that’s today powering social networking software like Twitter alternative Mastodon, the Instagram-like Pixelfed, video streaming service PeerTube, and others. The news was revealed in a response to a Twitter user’s complaint about Mastodon’s complexities. Automattic CEO Matt Mullenweg — whose company acquired Tumblr from Verizon in 2019 — suggested the user “come to Tumblr” as the site would soon “add activitypub for interconnect.”
“Don’t stress,” he said, before clarifying that Tumblr first has to deal with the waves of new users coming in right now from Twitter, but that support for “interop and activitypub” were due to come “ASAP.”
In short, this announcement means Tumblr would move from being only a niche blogging platform to instead become a part of a larger, decentralized social network of sorts — and one whose user base has grown in size in recent days
