The #Ghost people are doing excellent #ActivityPub marketing with their weekly newsletters, such as today’s. I don’t agree with some of the details of their points of view, but that doesn’t matter in the grand scheme of things, they are doing a great service educating potential users beyond the niche of today’s typical Mastodon users.
