We don't do this either (I hardly look at the thing at home), but just a look at the other parents bringing in their preschoolers at school is depressing. Half of them have their phone out, and the number of parents you see pushing a pram or stroller with a phone in front of them is absurd.
It's apparently also a hangout spot for (self-awarded) gold star internet parents who love the smell of their own farts and think anyone else wants to smell them.
We are a minority.
