I'm in the same boat...honestly, after yesterday came and I didn't receive a phone call, I just went ahead and assumed that I didn't get in. I think it's better for my peace of mind. I'm guessing I'll get the official rejection email in the next couple of days.
I saw that posting too, and immediately panicked! People did start hearing from Stanford between Feb. 11-13th the last couple of years (not that I'm obsessively searching the results board or anything), so maybe it's legit?
