Same here!

I don’t think it’s exactly the same on lemmy – you can’t seem to sub to an entire instance, for example – but there’s at least some similar capability.

For instance, I’m on kbin right now, so when I click your user name I go to a kbin version of your lemmy.world profile page: https://kbin.social/u/@SubsAndDubs@lemmy.world. It has the option to block or follow you, which should show your posts in my kbin feed. As far as I know, Lemmy can’t do the same with kbin users. I haven’t found a way to follow other lemmy users either, except on kbin.

But on lemmy you can sub to lemmy or kbin communities, even if they’re on other instances. On lemmy.world, RedditMigration has the address https://lemmy.world/c/RedditMigration@kbin.social. So it seems to be a community there that just pulls in from the original at https://kbin.social/m/RedditMigration@kbin.social. (No idea why it’s like this.)

So if your main instances was, say, beehaw.org, you would search for !RedditMigration and you’d see that community pop up in the results. You can subscribe to it that way and it would be in your subs list on beehaw. The same should be true of kbin magazines/communities.

It looks like each community on lemmy has their address posted next to the subscription box, so you can paste it into your lemmy.world search and sub to anything you want regardless which instance it’s on.

In theory this is going to work (maybe?) with other fedi services like Mastodon, but I suspect the admins and devs have to build a lot of things, so it may not be around for awhile.
