Yeah my rule of thumb while cycling is, if it's an empty street i'll slow down so i can scan the other 3 sides and if it's completely empty i'll roll the stop sign. If there is a car/pedestrian, i'll come to a complete stop.

I feel like I would be a lot more frightened of getting hit by cross traffic (with right-of-way) in the rare case where one mis-judges whether cross traffic exists. I've had enough close calls (or times when I mis-judged whether someone was going to blow a red light/stop sign) when driving a car that I feel like doing rolling stops on a bike is nearly suicidal.
