Education costs money. Ignorance costs more.
FYI: There is a new tool called 'Mindomo" http://www.mindomo.com/ which can be used to draw your own mindmap.Pierre
Thanks for the link. That'll come in useful for something I'm planning.However, the interesting thing about wikimindmap is that it draws a map for you based on the structure of Wikipedia pages. Obviously this has huge disadvantages, but it's an interesting place to start if you don't know much about a particular subject (or you want your prejudices confirmed).
