This article on informit.com from a 'non-sensory and non-visual person' gives a great summary of some of the benefits of mind mapping with MindManager. It looks like mind mapping is slowly becoming more and more mainstream. Some of my favorite snippets.
"for one thing this client had seen the tool used by a number of other executives at a high level conference; that's how he got interested in the product."
"mind "mapping" is different from flow charting (Visio) in terms of its rapid response to mental stimuli."
"it visually represent ideas in a way that allows you reorganize them later, hold people accountable, and see the "big picture.""
"a mind map branches out in an organic way, allowing you to see relationships and work in a less structured and free form way"
"Mind Manager takes the best of Visio and OneNote (the searching and tabular versatility) and combines it into a powerful visual brainstorming and organizational tool."
"If you're a visual thinker who works on tight deadlines with complex ideas and projects, I suggest you try Mind Manager Pro — you may never use an outline again."
