As someone who creates content and curates (and keeps an eye on how much I "earn") I have to say you can still earn a hell of a lot more from content creation than curation (and the tribes have created more ways to earn). I have to say if I want to earn from curation I would just go to trending page rather than upvoting other posts, but I don't (and that is not what most curators do). Curation isn't about making money (there are better ways).
