@Gargron @w3c I doubt #Bluesky will embrace #ActivityPub out of pride, & #Tumblr will probably join the #Fediverse in 2025 or 2026 (based on their current pace).
I do believe that we will probably see more government institutions, private organizations, political leaders & famous celebrities who are running #WordPress enter the Fediverse (via the plugin).
I know #Flipboard will enter the Fediverse soon, but I am not sure when (or if‽) #PostNews & #Flickr will join.
