My personal posting philosophy is not to say anything I would say to that skater/coach/poster's face in person. I know its bothersome when people attack me via voicemail, email or Facebook comments (I work in a job where such an opportunity exists), knowing that those people really wouldn't say that to my face.
So I wouldn't like it if someone told me to quit my job w/o knowing my personal situation, so I avoid doing so here.
Thank you, Mrs. P; I totally agree with you, and cannot believe some of the things I'm reading in this thread!!
