I really don't understand why people think 50/50 would benefit Steemit, it certainly would benefit curators (the ones with large SP) but the authors? Rewards are a finite daily resource, say 80,000 Steem daily (this is just a number, I don't know what the reward pool is), right now authors would get 60,000 with 50/50 they get 40,000 and that's it, curators would jump from 20,000 to 40,000 why would they change their voting habits if all of a sudden they will be getting 100% more for what they are already doing? So yes whales and large stakeholders will benefit, no one else will.
