I don't need to hear profanity laced tirades by 16 year olds. I would rather just school them online and not hear anything out of them. Plus, I have children who don't need to hear this sort of stuff. If there is no way to mute all strangers (there was with the 360), I'll have to return this puppy or not spend a dime on games etc until this is supported. This UI is absolutely horrendous. Doesn't seem to be gamer oriented at all.
