Tent.io brings an important question. Can distributed social work as well as email?
Imagine a scenario where you sign up on service A and your friend signs up on service B and you're both able to message each other without worrying about things like SSO or making profiles on those social networks.
Also, can ADN act in such a manner? Can social networks built on ADN allow frictionless cross posting? Will that be a model that'll just work?
