‘Simple’ question – refers to anything. When we talk – or explain – or in a simple case, design a system for people to use. Do we just make something extremely simple and intuitive? or try and think of every need the user might face?
What I’ve learnt is that the goal is for it to be very very simple! It so happens that it eventually does end up being complex. And by some chance, if more than a billion people are using it and it still is as simple as typing whatever you want in a plain white text box and still getting results – then you’re going to make billions – just like google!
