Thanks for replying,

Sorry, I wasn't clear; internally it's a meritocracy - you perform well as a curator at finding posts, you benefit from more submission slots.

However, id like to make a point on the rep thing with a recent example....

Rep hasn't been part of the guidelines for a long time. It's all reward based. There is the inherent probability that high rep authors receive more reward, hence they tend to not get curie upvotes but it does happen. It's not like the current curie upvote would particularly help out the majority of high rep authors anyway; the average curie upvote at the moment is around $30-$40 which is pittance compared to what most high rep authors are getting (high rep being 60 or above from my point of view)
