I’m on facebook. It connects me to a number of authors and artists, which provides wonderful entertainment.
However, I hardly post anything myself. And I NEVER post anything about work.
Yeah, but the elementary teacher who posted topless pictures of herself drinking beer in the Bahamas, well, that's the kind of stuff that will get you in trouble.
I agree with you. Never talk about your job, or your co-workers, or your boss, or your bridge club, or...well, anything you have to face again.
BTW. If you apply for a job, one of the first things they will do is check your FB. So, if you are cursing your boss or linked over to AA or NA or the KKK, or are drunk and topless on St. Patty's day, they will know it right away.
