Without the early incentive, you'll just vote for all the most successful posts late.

We agree, but no one knows how to fix that. Not Facebook, not Reddit, not Twitter, etc.. It is an industry wide unsolved problem.

What would you think about each day having some sort of "bonus" vote carrying a bit more weight. Maybe 3 a day that would give you a higher curation reward. I don't know if that is feasible, but I think it would be something interesting to explore.

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.
