Wow! Great article David! Yeah, the visual aspect of a mind map is really powerful. I only discovered mind mapping last year (wish someone would've shared it with me in my early days of developing; would've saved me countless hours of re-work).

I use SmartDraw (http://www.smartdraw.com/training/how-to/mindmaps/). I'm one of those people that prefer keyboard shortcuts (i.e. ctrl-c, ctrl-v) and really like how quickly I can document our brainstorming sessions with the keyboard shortcuts in SmartDraw. And being able to quickly transform and distribute the mind maps as gantt charts to my team is a huge time-saver.
