I never liked that method because the meat ends up tasting like fresh coals and not the smoke flavor you want or look forward to when smoking meats. The reason why most people light the coals all at once because it allows the outside layer of "coal" to burn off and not affect the taste of the meat. The whole point of smoking meat for me is the flavor that the "smoke" gives to the meat so for that reason most of my fuel is wood and a lot of smoking chips not coals. Smoking with coals will give you great cooked meat, but it will never has the same taste of meat smoked with nice mesquite, hickory, or apple wood.
LGHT is right on point abiut that smokey flavor that wood can produce. If you have to use charcoal, use some chips/chunks of wood as suggested by LGHT. Red Oak, Hickory, and Mesquite are all good flavoring woods, especially when combined with fruitwoods when smoking beef. It's all good my friend..
