Because I am aware of my incompetence to manage Hive's books, I pay as little mind to rewards as possible. I vote on comments as a matter of courtesy, or (on comments on other's posts) to indicate agreement, whether I am providing ancillary comment or not. I vote on posts to support authors, appreciation for their efforts related in the posts, or as agreement with a particular point made in the post.

I never, ever vote because I have VP that needs use, or to increase my HP through curation rewards. I consider curation rewards nothing but derangement of curative intent, replacing pecuniary interest for all others. I always manually vote, and have never even considered automating my voting in any way. I reckon voting on Hive particularly expresses social interaction, and utterly, completely, and absolutely oppose automating social interaction - other than as is necessary to extend our reach to interact with more and diverse people.
