Thank you for the illustration of the derivative work in the rewards pool. I am not sure that changing the formula however would get the results we want: the growth of the block chain, more users, more ad revenue, and a higher value for steem.
I would like to see a better balance between rewarding those who do the creative and supportive work for the block chain and those who invest but mainly reward themselves.
I would like to see a minimum vote power instituted for those steemians in good standing. For example, everyone gets say 10 one cent votes a day to use but they cannot use it on themselves. This would encourage users to network, use the block chain more, and make newbies feel they have more impact on the platform. Now that we are an ad-revenue based platform/block chain, we need this.
Some of that ad-revenue, once running costs are met, could be used to reward those steemians that perhaps are not as heavily invested in steem but have invested considerable time and intellectual property building the block chain. Better still if they happen to be both invested intellectually and monetarily.
We really need to have our view counts back. Right now the only reliable evidence of proof of brain visits is the comments section. We need to encourage the use of our platforms and reward those who use it as intended. More eyes of the page will drive up the value of steem and rewards for everyone, no matter how we divvy it up.
