@freemo probably the biggest obstacle would be that algorithms require telemetry and fediverse has a vast over-representation of privacy nuts that religiously believe all kinds of telemetry are evil no matter what they're used for.
@realcaseyrollins @freemo true, not all algos are personalised like trends on Mastodon. But all that are require at least tracking what you like to work at all, and tracking what people that liked the things you like also like to be actually good. I don't know how iTunes smart playlists work, but even if they manage to only work from the context of the rest of the playlists / rules on your side and tags and the like on potential recommendations' side, it's not something that would work nearly as well for social media posts.
