What is the relationship between mastodon and lemmy.world
I have an account on a mastodon instance and I read that I could access the threadiverse from there, but I didn't find any way to do it that works. What is the relationship between these things?
They are on the same "network", but that only means they use the same format to exchange messages. It does not mean that they work well together. The Lemmy UI is much better suited for posts with large discussion threads.
Basically you can treat them as separate for all intents and purposes.
