> “The Social Graph” and its associated apps should be like the internet, distributed and not confined to one company’s servers.

It is like this though. Any one of us can re-create our social graph in a heartbeat on any of these services at any point in time by importing our contacts and letting the network present us with our associations at the moment in time we want it to.

I've done this with linkedin, having zero presence there until the moment I wanted to network in a new area.

I've done this with snapchat

Telegram

anything I want at that point in time

there is no need for continued presence on any one of them since you can come and go as you please with new profiles and reconnecting to existing associates.
