I'm a late convert, having finally joined a few months back...more so that I can keep up with former coworkers/friends.
But...BATSHIT FUCKING NUTZ patients are not going to get the OK to be my FB pal. Now, I do have some former patients as FB friends. But they are all level 1s (see this post) and some I knew as a person before she became my patient.
Last thing I need is a level 4 or 5 knowing personal info about me!
