Uber CEO's mother dies in boating accident

There is a second reason. Uber has become so controversial that it is impossible for it to be mentioned on HN without the thread filling up with angry comments against both it and its CEO. The idea of that happening in a thread about someone's mother's death is pretty nauseating. Yet it would happen, not because any HN user is so bad that they'd do such a thing intentionally (in person, say), but because internet forum threads are a crude instrument that cannot be guided with any delicacy.
Therefore the users flagging this story are right to do so and it should not have a place here.
