@WedaleBooks 😂 nothing rookie about it! I often forget! It’s just that here it’s much more important for reach. People follow hashtags for what interests them & using them in your posts means your posts will be boosted automatically to everyone who follows the particular hashtag/s you have used. And bookish stuff is quite big here hence e.g #Bookstodon

(You should also know that mini-lectures about Mastodon usage are also a thing 😉)
