Caring about the receiver - this is what is lacking. The sender should think about the receiver and send only stuff that would be interesting to him, or help him even if he does not like it at once. The sender should have means to target his messages only to people who would like it. The receiver should have means to express what he liked and what he did not. Channels should be negotiated between the receiver and the sender.

I call this 'social routing'. I hoped that Google+ would do that - but they only covered half of the idea - they let the sender target the message, and they let the receiver choose their sources (in a tangled together way) - but they don't let them negotiate the connection.
