Really the biggest effect your home instance has is who you’re defederated with. Your instance admin can choose to defederate with an instance at any time, blocking your communication with that instance.

For most instances this isn’t a real problem because nobody defederates without a clear reason, but in some cases like Beehaw users were upset that the admin decided to defederate with instances they use.

I recently signed up and didn’t know where to park myself. So I got accounts on both lemmy.world and beehaw.org.

From lemmy.world I’ve added to a few of the beehaw subs that I’m subscribed to there. But I can tell you I see different content in my lemmy.world feed.

Don’t know why. A delay in the content making it over from beehaw to lemmy? But my home feed certainly looks different in both (even subscribing as closely is I can to the same feeds).

So for now I’ll stick with both and see how the dust settles.

or you can join a smaller instance that beehaw has not defederated and interact with both beehaw and lemmy.world communities

Doesn’t defederated mean cut off? Because I certainly get beehaw content at lemmy.world. Just when sorting by “hot” seems different. Then averaged over a bunch of subs, my home feed is quite different.

Anyway 🤷‍♂️
