I don't think people realize how hard it will be for existing companies to redesign their business systems and models. The external simplicity of Steemit belies the incredibly complex and unique Graphene blockchain software and ingenious economic design. It may be extremely difficult for any existing platforms to replicate, no matter how much money they have. Don't forget time and perception is a factor. Time they simply do not have. Censorship has already tarnished certain platforms..... However it pans out. If there is a pressure on systems to compete to be more open, with more integrity and able to benefit more people around the world, then good for Steemit and Steemers!
