When I work on a project, I usually whiteboard it, then work in outline mode of Microsoft Word. I will sometimes use a mind map program like MindMeister to capture my thoughts. The benefits of the Word outline mode and the electronic mind map is that I can move whole sections around and show scale at the same time.
Prezi does all of this AND allows me to draw a path through it so I can show others. What a fantastic tool. It is THE “mind map” and presentation tool. I hope you agree.
