It really depends on the location and with whom I'm riding. If I'm riding in the city and by myself or with a small group I will stop.

If I'm riding with the club, which is notorious for blowing stop signs and I'm traveling with a big group I follow the group. If they stop I stop, if they blow it I blow it as well. I know that sounds terrible but the one time I did stop when the group ahead blew a stop sign I was run over by another cyclist. Thank goodness the only injuries I suffered were a lot of deep bruises on my lower back, hip and legs.

If I'm riding by myself in the country it depends on the intersection. If I can see in all directions and it is clear I'll go through (foot is unclipped and pace slows). If I can't see I really slow down and will often stop.
