[replying to your later reply]

Anyway what you're saying is that you for example would choose steemsports/games to vote on simply because it's what you like and not because it will in some way benefit you, correct?

That's not only a hypothetical, that is usually how it actually works. I don't often enter the contests even though I vote on the posts and I often vote so late that my curation rewards are little to nothing. I'm voting on their posts because I think it adds value and they have invested and are investing a lot in improving Steem and it is good for Steem when people and businesses do that.
