The WoW Armory recently got a nice face lift, but introduced activity timestamp. This feature is a serious privacy controversy when people can actually monitor your gaming schedule trends.
From gold farmers to your job's boss and your mom can see when you have played. Gold farmers can play when they know you aren't around, your boss can find out you played WoW during your 9am - 5pm schedule, and your mom can find out you were playing after bedtime. What a nightmare!
