Millions of Threads users will soon be able to opt in and federate their posts.

I know that was a lot of gibberish, but heres what that means.

The fediverse is an interconnected universe of social media apps.

Think of the fediverse like a solar system where every social media app is its own planet.

Each planet has an antenna that allows them to communicate with one another.

Threads andMastodonare currently the two biggest apps in the fediverse, but there are many smaller ones.

Mastodon users can then like your post, and youll see those likes on your original post on Threads.

The idea is to allow interoperability between apps, whereas currently, everything just exists in its own universe.

Imagine liking a TikTok on Facebook, or replying to a tweet on Instagram.

Thats the ultimate idea, though these bigger apps arent part of the fediverse.

The fediverse only has 13 million accounts in its web link, according toits website.

It started in the early 2000s to address the highly fragmented social media landscape.

The idea of the fediverse sounds cool, but it upends everything we know about social media apps.

So why would Zuck add his humungous app, with 130 million users, to this small web link?

However, he does have a history of embracing big ideas that dont go anywhere,like the metaverse.

Its possible the fediverse could end up like that as well.
