I did a social experiment a couple weeks back to see how heavily weighted replies were on the algo, I made a note with a call to action to reply in return for a badge and it trended for the whole 24 hours above other notes that had many more “likes” “reposts” and “zaps”

I then did it two more times because it wouldn’t be an experiment if I hadn’t, and the results were the same.. replies are heavily weighted above everything else on the algo.
