You can send a `Move` activity that will tell other instances that you moved, so people will (depending on their server) refollow you automatically. We (= people working on ActivityPub systems) are thinking about ways to create identities that don't belong to any one server, so you wouldn't lose your account even if your server went down.

In general, systems display what they can. Pixelfed, Mastodon and Plume mostly send `Note`s and `Article`s around, which are easy to display in any of their respective interfaces. Other types like `Video`s will usually be displayed as good as possible, with a link to the originating instance. Unknown activities are usually just thrown away by the receiving server.

(Not the person you replied to) Thanks, this was helpful. The fact that there's a common activity vocabulary helps me understand the usefulness of an ecosystem of ActivityPub apps which focus on different ways to write and view posts.

Thanks! Integrations don't sound perfect, but I guess it would be unrealistic to expect perfection given the nature of the implementations.

Identities that could be somehow owned independent of servers would be a game-changer, I think.

Thank you for your work, and congratulations on 2.0 ;)
