How will communities change a lot? They will have two choices, issue their own coin to sell FOR STEEM, with the main possible investors being the same whales gaming the system now, or continue to draw from the same rewards pool. If you read the white and blue papers and even listen to Ned's latest talks, he constantly makes reference to the quality of the content? Why? Because the quality of the content ESPECIALLY content that is internally promoted, is the value of the site, and the underlying value of steem itself.
