It is a mix. I'm certainly interested in my own benefit which leads me to not only vote for what I think will be popular but also to incentivize good comments and conversations that are unlikely to get attention but promotes a good experience for new users and struggling authors. I'll often "sponsor" certain topics or authors I think are under appreciated or that I think will draw in more people to the platform.

I believe the largest gain I will see by curating is through an appreciation in the price, not necessarily in accumulating more rewards. So promoting a wide diverse quality trending page is my primary concern. Making as many people as possible happy with their time spent here.
