IPV6 is really needed to create social media distribution with customized privacy. Example, use a smart phone as the actually distributing and access control system. This way a person can instantly block and know who is accessing their content too. End to end encryption communication with content distribution.

Of course this is more into the future when Cellular ISP are better with less strict data caps and better upload speeds along with not having to connection to Apple or Google or Amazon for Voice to Text / Command / Action solutions and smart phones actually have a viable storage capacity.
