Added my vote but I agree with cthawley’s sentiment that it should be narrowed down to the use case where, as a curator, you want to surface other curators for the purposes of curatorship.
I don’t think an everyday user simply wanting help with an ID generally needs to surface curators on a leaderboard. A curator showing up on a leaderboard may or may not actually be an expert on the taxon in question. For example, I show up in the top 5 ID’ers for Kingdom Fungi observations in my state, but 100% of those 500 IDs are of “Kingdom Fungi” or “Class Agaricomycetes” (or something in between) – I’m simply helping things along to those that can (hopefully) ID them.
