A simple tip, in that it doesn't mention distributed thing much.

If you're into expanding it, a few days ago I saw a great explanation: your handle is like your phone number, and the instance is your phone provider. So you come pick a provider, and they give you (or let you pick) a number: the same for e.g. mastodon: you pick an instance, and then you pick a handle there.

You can still call people at other providers/instances, you can send each other messages etc, like in the phone analogy. Even posting to local vs federated timeline has some (for us invisible) price difference.

Finally, between some providers e.g. in different countries, you can send one type of stuff but not the other - like MMS messages. And on fediverse it is similar, some things like #funkywhale or #peertube allow posting audio or video, but mastodon readers cannot get that.

But I'm not sure if it's necessary. I just liked it a lot.
