1. Author is rewarded only when/if curators upvoted the post
2. Curation rewards are distributed between all curators who voted, so even at 75% share, curators are likely to get way less, then the author (per person, especially when many people voted)

Another example: an unknown musician created a song; but if nobody hears it, creator will not get anything. And then an established influencer comes and promises to promote it, but collect 90% of all earnings. What is the best course of action for the musician? Should they collect 100% from zero, or 10% from something?
