other ways to actually make it worthwhile for humans to interact in Steem ecosystem rather than just sell votes passively
it could be just the semantics of how I understand this, but that sounds exactly like saying "vote for content the way the community wants you to vote for content"
One of the reasons STEEM has additional value for investors is the possibility of passive income PLUS the potential likelihood of market value increase.
you either have to remove curation rewards for curating, or face the likelihood that some people will game the system for their own best ROI. when you remove curation rewards, whether passive or active, you remove the value for some investors.
The best way for any creator to make SP is to network AND to create quality stuff. I'm not good at networking, but I realize it's still the best way.
