I agree if Steemit only has 10 or even 100 whales controlling the reward pool, it will make it harder for smaller accounts to grow and will be bad for the platform. It wouldn't be the DECENTRALIZED if we have a small group of people controlling large amounts of steem. However, I don't yet see a fair way to control this, I think our platform is so new and growing so quickly, we just need to wait and make our own growth early.
