I've always had trouble getting on the mind mapping bandwagon. I'm sure this is partly because I am extremely comfortable in outlines and do lots of project planning in my task planning application. I think another reason, however, is the price and learning curve required by most mind mapping applications.
Recently, I started making mind maps in MindNode Pro. This OS X application is very simple and I've been able to constructively use it with almost no time spent "learning" the program. I know there are more feature rich mind mapping applications out there but right now I am really enjoying MindNode Pro. The $15 license fee combined with the shallow learning curve makes this one easy to try on.
