I think you should get more curation rewards for voting something that is not expected to do well but does( value investing in my field)  For instance if a poster averages 5c a post and then nails it , the curation rewards should be higher for the value of post above 5c ( or Lower if under 5c) This encourages  posters to read, consider if this is really good and not just reward posters with good track record. Maybe it's a 25% bonus  or penalty for voters in first  30minutes on all value above the  average. The later voters would be he source of this reward.
