There was a discussion recently in a Toronto (Ontario, Canada) blog about "traffic/noise calming" stops and "right-of-way" stops. The author wanted to suggest that since bikes aren't part of the traffic/noise calming targets, they should be allowed to roll through such stop signs but, like all vehicles, be required to stop at "right-of-way" stops. It makes sense but might be difficult to monitor.
On my morning commute when I am on the road often between 6:00 and 7:30, mostly on residential streets, I roll, no blow through, most stop signs but only ones that I can see every direction for at least 100m (yd). If I can't see that far, I'll slow or stop if necessary.
