So #Tumblr has 135 million (!) active users who will join the #Fediverse in the next few months (if not sooner): https://www.tumblr.com/press
For comparison #Matrix has 64 million active users: https://news.itsfoss.com/matrix-sixty-million-users/
Tumblr also plans on adding Matrix support (probably after activating #ActivityPub upon the site).
How will #Mastodon servers handle the influx as Tumblr is a very media rich website (more more than #Pixelfed IMHO)‽ Any #MastoAdmin want to weigh in‽
@darnell Beginning of the end of the defederation dramas. You'll either federate with Tumblr and be part of the biggest part of the Fediverse or be in a pocket universe. More surgical tools for moderation will have to be developed.
@acjay Yep! I did ask Tumblr if I could beta test ActivityPub (I subscribed to some of their beta testing already). Hopefully they say yes! 😂
