The problem withSteemit is that pay to much for a single post, and really nothing to 99,9% of the community. And in my opinion this imbalance will persist for at least two years more because the way steem power is distributed.
Steemit created a really good idea with a lot distribution imperfections. So, if you take a strong crypto currency as Bitcoin and make an small evolution to make more fair the rewards to content creators, then you have a mankind type of change. The contents creators does not want thousands of dollars for one single post on their life, they prefer tenths of dollars for each post.
A exact copy of Steemit using Bitcoin is very difficult because of the micro payment problems related with the fees of the miners transactions, but if you make payments with the complete rewards, for example once a month, this problem do not exist.
Steemit is in the first step of this new kind of social networks and the future has to be written.
The most important thing in a big network is not to hear the shout of the most influential and steem powered but the noise of the masses that represent the network indeed...
