I’m not sure why I haven’t mentioned it sooner, but Mindomo is a Flash based mind mapping application. I’m using it now to organize my Maikeru On Game notes, and it couldn’t be simpler. The interface is modelled after the Office 2007 ribbon, so if you’re at all familiar with the latest incarnation of Office it shouldn’t take any time to get used to. Even if you’re not familiar with mind mapping or Office 2007 the learning cruve is almost nonexistent. If yuo’re looking for a useful brainstorming tool take a look.
