Divergent Thinking, what is it again?

A main concept introduced in intro class (Jan7) and again in class 2 (Jan14) is DIVERGENT thinking. This is related to mind mapping or even brain-storming.

Divergent thinking is a way to generate ideas in a whole, non-sequential, quantitative and non-structured way. It's a way to get projects creatively underway (see David Allen, Getting Things Done: The Art of Stress Free Productivity).
