I track discussions about mind mapping on Twitter and in blogs, and I often hear or read the question "Which is the best mindmapping software?" Anyone who gives you a single, immediate answer either knows you and your mindmapping activities very well, or is likely recommending the one that they've become familiar with themselves.

wiki about mindmapping with cathegories, uses, etc... a nice mindmapping resource
More and more tools get online...
I love mindmaps and this wiki introduces a large range of tools to create them. Many are free and I can't wait to try them out.
