I sometimes pluck a spoke as part of the 30 second bike check. I don't do it for accuracy (wheel building) but to look for glaring problems. A truly wonky spoke will stick out like a sore thumb using this method. If I find a problem I then slap the wheel in a truing stand and grab by tensiometer to find out what is really going on with this wheel.
