I have two accounts I use (and two more I don’t from exploring the fediverse a bit), beehaw and lemmy.world. Beehaw is nice, but doesn’t have the nisch communities that are on lemmy.world, and with the current federation situation two accounts are easiest for me at least.

Btw, Liftoff for Android works really well with multiple accounts. You can merge it all in one feed and it uses the right account depending on what server the post is from.
