Philosophically I love the idea of letting users be in total control around the notification volume they get.
There is a balancing act, between giving 100 toggles (disable likes from Jane but allow everything else) and giving the right toggles.
I do wonder where we see this fitting. @awesomerobot I wonder if we have outgrown the ad-hoc way we allow people to control what they are notified about and should offer a central / consistent story here with more fidelity.
