Useful compact image to explain to people who don’t know the fediverse.
On the other hand, it makes me think - why are so many boxes necessary when we have activitypub? Why should anybody need to go to a different tool for each service, why no one-stop-shop software, at least for casual beginners?
(btw I’m aware mbin and friendica had that concept to some extent, but don’t try to cover everything, and I fear that if they did and it took off, scaling-up might be an issue with such php-based stacks).
So, instead of re-implementing 2nd-hand concepts from big-tech, fediverse “killer-app” should be that you just need one identity in one place - you still have to choose that instance, it’s decentralised, but it can do more than any of those big-tech services.

Good collection. Will loops have an iOS app soon?
