content: One thing I thought was interesting was it notifies me if any of my contacts install it which seems like a minor privacy violation but I guess it makes sense in that it's better to know if it is secure to send a message to someone or not. I've been a long time user and fairly recently, it notified me that a couple of parents in my son's class had installed it right around the same time. It was a guy and a lady. It could be that it's been getting more media attention but I decided to assume they're having a secret affair and they're doing everything to cover their tracks.
