We don't need to look to TikTok and so forth as inspiration for "monetizing the #FediVerse ".
Instead, think of small online businesses. My favorite example of this is the #ttrpg industry - the majority of companies are very small indeed.
And for them, it is vital that they can interact with their fans and customers. On #Facebook , they can do that via Facebook Business Pages, which provide a feed that regular Facebook users can interact with.
I want that kind of thing for the Fediverse as well.
