@FrazzledBrynn this is one of those fedifacts that i see people see semi regularly, usually in the context of “i dont get it, faves are great!” but have never actually seen any evidence for
my theory is that people are just confused by the way boosts/replies are much more likely to federate so if you look at a post you’ll see every boost & reply your instance knows about, but only the faves that also came from your exact instance. which means the fav count can look p teeny even when its actually 3x higher than the other counts from the post authors perspective!
