Well, what will happen next is:

Someone will develop internet 3.0
Internet everywhere on earth, unable to be blocked by anyone.

After that, people will start having a social media server. Think of it as being your own personal wall, and it really is yours. You own the server. Then people who are your friends (your server talks to their server, and has lunch...) post stuff to your server, or your social media browser goes out to all of your friends and pulls stuff from their walls.

And there is a competition in social media browsers. Ones that sort into various circles. Ones that get you the latest as fast as possible. Ones that have a puppy in every screen...
