The thread about the maps on Wizards' site made me wonder if anyone has done a detailed discussion/instructions/suggestions on making maps that make sense. For many DMs, when they create a "dungeon" or other adventure setting, they might find a map somewhere or draw out some boxes on grid paper and figure out later what each area is used for. Sometimes this works just fine, other times, you get something illogical that has players scratching their heads. 
So, any articles on mapping? Any tricks or special techniques you use? How do you design a system of natural caves versus humanoid-made ones, for example?
