Hi, as you know from being a MAP member, upvotes on their own have a limited supply. I do not have the luxury of 100-500k SP to make a significant difference to someone's post rewards, hence MAP itself (and me in particular) have leveraged knowledge to help minnows make themselves visible in their best niches.
I have used the analogy before that that kind of curation work is akin to a digital content agent. But that agent needs to find a publisher for the writer. And publishers do not have only one department; literary fiction or popular science rarely make much money compared to pulp, but the profitable sides support the less profitable creative or speculative works.
So, I will upvote the pulp only because it makes a profit that can further support upvoting curated content.
