see, i read that too, and i've tried that on my ss mtb, with mixed results. i mean, you might get lucky and it might work... for a while. and you can achieve better results by clamping a serrated (sp)/crown washer against the dropouts. but the truth is, you need a lot of clamping force to keep the rear wheel from slipping under heavy torque, and in most cases, a QR (even a really good quality one, closed cam, cromo, etc) will not have enough clamping force.
