The (ideal) most reasonable approach for public information organs, in my opinion, would be to use all the channels that are available - Mastodon, Bluesky, Threads, but also X for the share of people that can’t be arsed to move (or don’t want to, because the people and communities they care about haven’t). I’d even count Facebook, Instagram, Reddit among those channels, as much as I resent those companies, as well as Lemmy and the other fediverse services (I’m not super informed here), a blog, RSS feeds, maybe an email subscription service too, just to be sure.

In fact, I think diversifying your presence would be a great thing in general - platform exclusivity is turning out to be a quite toxic and disadvantageous concept. Well, it has been for a while, but it’s starting to become more visible.

The real restriction is of course the technical infrastructure and personell to maintain all these presences. You could use of a content distribution system that takes a picture, a long text and a short summary to generate appropriate posts for all these platforms, but you’d still need people monitoring and responding on the various platforms, ideally people sufficiently familiar with the respective culture to communicate effectively.
