You could make an argument that this whole thread with nearly 800 replies:
iNat Milestones
is about gamification, but I see it differently.
To me, it’s about motivation.
In true gamification, the motivation is EXternal: points, badges, leaderboards, etc.
But for most iNatters, IMO, their motivation is INternal. The “gamification” elements are just fun ways to keep score. iNatters love learning, and they love contributing to something bigger than themselves.
So your question can be a bit nuanced, as it requires looking within yourself, and asking WHY you do what you do!
