Patience.
I think it is all well and good that Google / Facebook ends this mad goldrush... Or at least try to curb it a bit.
We need better regulation, and stronger investment safety - and actually I think that is pretty pathetic that is going to privately owned companies like good and facebook that starts this move towards more responsibility.
It is also a strikingly strange thing to happen.
When has those companies ever said no to money, unless it was downright illegal?
