My tipping piont:
starting this job and realizing that my old obsessive message board was blocked and this wasn't. Looking bad, this board is much better! Even at home, I hardly go on that one anymore.
My tipping point for off-topic and snarky discussions:
after the Sept LSAT and waiting for score release. I was so antsy that I needed distraction and y'all provided it. Plus, I wasn't an LSAT virgin and could make fun of the silly n00b questions.
