I'm looking for a list of mind-map/brainstorming software that are easy to use, intuitive and practically applicable across a wide range of projects.
Thus far I have been using IHMC CmapTools software, which is pretty good in most cases but not quite right for some. I'm looking for alternative programs similar to this, that may be better suited to other projects.
Please suggest some brainstorming and mind-mapping software that you have found useful, and if you wish to, give a brief description of what makes it useful.
Preferably open-source and Windows compatible, though this list is for everyone so feel free to suggest software for other operating systems, and include paid software if it's suitable.
