This is for when there are multiple comms across instances, for example there’s !science@mander.xyz and !science@lemmy.world and a .ml version

Same with !memes@sopuli.xyz !memes@lemmy.world and the .ml version

If your interest is in science, it costs you nothing to post to mander.xyz’s version and is a cheap contribution to the overall health of the Fediverse

If the only version of a comm is on .world, that’s fine, that’s not what the meme is about (though if it’s on the Tankie Triad, I’d encourage you to create your own community on your home instance, which also contributes to your home instances growth)
