Good to know about the hashtag posts to Mastodon (didn’t know that before). Hmm, it could be there are two different types of mbin “posts”. I just saw a mbin post asking about the difference between threads and microblogs: https://threadiverse.link/fedia.io/m/AskMbin/t/4407634 I vaguely recall Rimu talking about wanting Piefed to be interoperable with all the other major federated services, with the developers focusing on Mastodon currently.
