• They all implement ActivityPub which is just the protocol used to move everyone’s posts and such around to any other server that’s supposed to receive it. So yeah, you can use Mastodon to follow Lemmy or kbin magazines. You can also do the opposite where you follow Mastodon users from Lemmy/kbin. As long as the blog uses ActivityPub federation, you can ingest that content in to whatever other compatible service you want.

    I will say things get a little weird if you follow on a service that presents that information in a drastically different way, but it is doable.
