I think we need to work curation on another aspect what if you upvote "new" user then you receive lets say 50% of curation reward, if you upvote same person many times u receive less and less ( like with michele.gent ) up to zero . ( with cooldown reduction around 2 weeks) Then people will look into new users and content and not support only circle jerk . Just change 5 minute and curation reward only good for investors and not good for writers , think more deeper into this and dont be so greedy
