If you follow their lab, wip and their weekly updates (changes), you can see things being rolled out at a snails pace that are required for a fully fledged fediverse platform.

Polling, self moderation, notifications, etc. but it’s taking a looooong time…and there’s really no incentive for their devs to invest time in it, right? Because I won’t be seeing ads if I view tumblr content from my Kbin client for example.

I’m still having a hard time understanding why meta cares either. More audience for branded / sponsored posts?
