I know of one person in my office who got a ticket for not putting a foot down at a stop sign near Woodland Avenue in the Bay Area, CA. There is also one specific stop sign on Skyline that is supposed to have a strict police officer who cites cyclists for not stopping. These are known areas where cyclists had better stop.

I sometimes roll through if no one else is at the intersection - it depends on the location of the intersection. I'd never do it downtown - only in some parts of suburbia. If there is another car at the intersection, I make it a point to unclip and put my foot down - track standing leaves motorists confused about my intention and they try to wave me through. This usually doesn't work too well at 4 way stop signs.
