How are you discussing Social Media and The US Army to your Troops?

In recent light of the Social Media fallout from the Air Force Trainee to the Troops of the Wisconsin National Guard; How have you in the past, or in the wake of, spoken to your troops about Social Media and the Army Values?

Most soldiers in my length of Time in Service didnt recieve training on Social Media from our NCO's because it was not the hot button item it is as of late.  In some circumstances this could be the reason that the newer soldiers today are not recieving this advice from their leaders.

As an experiment, I showed our Trainees how much could be found on social media by a simple google search.  needless to say there were a few that decided Facebook was not their friend.

I feel that we need to ensure our soldiers learn that their actions on social media can have long lasting and potentially devistating outcomes.

What say you?
