Looks like it’s for feeds and the fediverse
the use of saying “it’s like email” is to explain how lemmy.dbzer0.com can talk to lemmy.ml, similar to how gmail can talk to hotmail and why in fact there’s lemmy.dbzer0.com and lemmy.ml (in the same way there’s gmail and hotmail). That’s it and doesn’t need to go deeper than that to be a useful comparison.
Well, it does if the person on the receiving end gets nothing useful from it. That’s my point, the confusion around Masto specifically wasn’t “why do people with different handles get to talk to each other?” That’s something that enthusiasts and developers care about and users don’t even notice.
The question that was being asked was “why do I need to pick an instance at all and what does it affect?” and that didn’t even BEGIN to explain the mess of themed instances, personal instances, effects of instance population on post distribution, manual blocks and defederations, what things did and did not make the leap cross-instance and the whole bunch of other details that matter.
A much better answer was “it doesn’t matter, just sign in to mastodon.social and call it a day”, but people used to be reticent to argue for centralization, because… decentralization!, so…
Ultimately the answer to that problem ended up going to Bluesky, which I think was very much a problem with both the design and the community at Masto. I actually think the Lemmy/MBin/Fedia Reddit-like corner of federated services is much more workable than a Twitter substitute. And it doesn’t even need a bad email analogy to kinda just work, either.
