@hmallett well, you're not using it wrong, you're just not aware of how it works compared to corporate sites.
With the way instances federate things and data is shared, obviously not everything can be federated or needs to be federated for different reasons.
In this case, favorite counts are used to determine trending posts on *your instance*. That being said, I'm not sure if that's caused by favorites not federating or vice versa, however, favorites are only federated between the instance that the post originates from and the instance that the favorite originates from.
So, if you see a post with a favorite count, that's specifically users on your instance favoriting it.
To see the real total count, you'd have to click "..." On the post and click "Open original page" to view the post from the original instance.
I'm not sure *why* they don't federate, but that's the reason you're not seeing favorite counts as much as you'd expect.
Hope this makes sense.👍
