Curation markets are the revolution. Decentralization is needed to prevent episodes like Cambridge Analytical with Facebook. Steemit, Relevant, Sapien have a lot to give us. I was studiying all these networks, reading white papers and comparing between them. Despite the fact that Sapien has not too much users yet like Steemit, I think they have an advantage because the Sapien network is trying to be more decentralized, considering token distribution. (90% of steemit tokens are concentrated in a few participants).
