capping rewards (instituting a maximum payout for all Steemit posts) has occurred to me also, but I rejected the concept because it deviates us from the natural law of imbalance / the 80/20 principle. IMHO it is far better to continue to allow the best connected people to keep earning 'unfair' $5000 payouts, than it would be to payout 50$ to 100 people... hmm. AND i also have a problem with flagging used as down voting. But I guess that's just me.
