One definitely needs to be VERY careful with Facebook if its being used to professionally network...and that's certainly not limited to the aviation community.

DISCRETION is the word - and as a pilot you not only need to show some in what you do and say, but just how much of those things you tell the world.

While I do have pictures of my company's airplane on FB that include registration number, everything is in accordance with our corporate social network policy (and folks, don't think nobody from your company will check you out, because they do). Additionally, my boss has rebuffed multiple suggestions about joining the BARR program and has told me point-blank that he doesn't care who knows where his plane is going - then again, he's a small businessman in a largely overlooked profession and not a captain of industry. This certainly doesn't mean other owners/operators feel the same way, and the prudent pilot should differentiate between the two viewpoints and know what NOT to post in a given situation for a given operator, and what NOT to post - ever...
