Tumblr will add support for ActivityPub, the open, decentralized social networking protocol that today is powering social networking software like Twitter alternative Mastodon, the Instagram-like Pixelfed, video streaming service PeerTube, and others.
It will always be the toot button in my heart (and because I mainly use Masto with Tusky on mobile, it still is).
Whatever happened to having a little fun? Posting a little toot now and then?
