If you go here: https://piefed.social/home/active/all
It just looks like its showing the most recently commented post. That probably isn’t how “Active” is suppose to work. On Lemmy, it works like this: https://join-lemmy.org/docs/users/03-votes-and-ranking.html
Active (default): Calculates a rank based on the score and time of the latest comment, with decay over time
Ok, in that case, we should call it “new comments.”
Yes I think you’re right. Thanks for pointing this out.
