I am worried about the 50/50 thing too. I spend hours even days on every of my posts. I always think I deserve more rewards on my posts.
The big whales take the the biggest advantage from curation. If it changes to be 50/50, I can't imagine whether the authors would like to make efforts to create great contents anymore.
Maybe I am wrong. Maybe I can't see the big vision. I am just worried that if the whales still upvote their friends most of the time after changing to 50/50, will steemit be better?
