@thomasfuchs I'm not strictly speaking, but I know historically Mastodon's userbase & developers have been against algorithms & especially one's that do any form of user tracking.
Hence, you could do the "top N liked/boosted posts from your followers over the past 24 hours" but not "you interacted with these posts so the algorithm suggests you look at these posts"
Though I think ultimately summary & algorithmic tools could be third-party via the API, instead of built-in
