@larsmb @eniko Friendica user here, and they have a pair of handy "algorithms" or three:

- "What's Hot": promotes posts based on recency, amount of likes and comments received by each post. No fancy-schmancy AI needed for that.
- "Discover": same thing, but for accounts that your followed people are following and you're currently not. Handy to discover new users you might like.
- "For you": it promotes posts from accounts you interact with, and from accounts that interact with you. It's also possible to manually tweak Friendica's affinity for an account, either making every post from an account you like appear in "For You", or demoting an account so that it never appears in "For You".
- "Quiet sharers": promotes posts from users that haven't posted in a long time but decided to do so recently.

Not sure why is such a list of "algorithms" so controversial - Mastodon already has to track the amount of public likes and comments a post receives in order to display those stats. And besides, Friendica does the right thing by allowing you to effectively mute a stubborn person you're forced to interact with a bit too much.
