看了条讨论串，关于Hubzilla与ActivityPub的互联。

对这则回复深表认同：

When the shortlived Great Migration to Mastodon took place last year, it was terribly cumbersome if you wanted to move instances — you would lose all of your friends again, at which point you’re required to somehow alert every account which follows you and expect them to go through the steps to add your new account. This is just too messy and for people who have spent years building their perfect social net, this is a pretty severe roadblock when one is forced to choose between a new instance with better culture but losing years of work connecting with interesting people.

这则回复也很耐人寻味：

Also note that email is federated, yet the majority of users have congregated around Gmail.
I predict that the same thing will happen with Mastodon, and that is not the type of future we should have.
Instead, I urge everybody to use P2P/decentralized networking, where even though there might be strong/reliable federated hosts, YOU fundamentally control your identity and it does NOT belong to a federated host.

而且很好地提醒了我：咱们早就拥有过类联邦式的在线沟通方式，那就是电子邮件。而Gmail等大型邮箱提供商则正可以视为一种大型“实例”。

“联邦式”是古早互联网产品就有着的形态，但直到互相独立、割裂的互联网产品越来越多，并形成寡头后，（一部份）人们才真正意识到联邦的必要性，这个概念才真正地被树立起来。
