Or to put it more generally, you have to look at your product or tool from the perspective of the laziest dumbest most unreasonable kind of people you want as the audience. You are not to complaint about how lazy they are, how dumb or how unreasonable, there are thousands just like them - shut up and do your job :-)

The mega pun is that if you are hard working, intelligent and reasonable this is going to be incredibly hard for you. You are going to need help from someone who is non of those things.
