I wish I could, for now the follow action is pending and then disappears: Discourse is unable to follow WordPress at this time.
I’m not sure it is doable at this point.
I’m going to defederate until we find an interesting approach that satisfies everybody.
That said @laurens we could as well mirror the newsletter: subscribing to it by email – actually the Fediverse Report category started like this, but I could not receive the subscription confirmation email. If you have a way to subscribe an email manually, that could do the trick.
What I like is that, for example, the ForgeFed: "New blog post! 💫 https://forgefed.org/blog/team…" - FLOSS.social came from the Fediverse, and I moved it to ForgeFed. I could as well activate federation there and follow the original actor. But indeed, @angus, if you can solve the orginal post vs. boost and we can easily select only original posts (and their replies), then this is a great way to engage conversation without putting the burden on existing teams and active communication channels: embracing them rather.
