I tried a few of the federated magazine links they listed, but I can’t resolve them in Lemmy. I know Lemmy doesn’t do person follows (yet?), so if that’s how they’re presented, that makes sense.
Are they working in Mastodon ?
I spot-checked a couple of them on Mastodon, and I can call up their profiles without an issue.
siiiiiiiiiiiiigh
But yeah, federation between Mastodon and Lemmy is pretty unidirectional. Users on (most) Mastodon instances can use their accounts to post to Lemmy and follow Lemmy users, but it doesn’t really work in the other direction.
