(Version 5.03)

APPSCOUT  Free?

Well, that depends on your definition.  
(Version 4.18)

TALLDWARF  The reason why CMAP is so good and I am going back to it after trying out "mind mapping" software such as Novamind and other online tools such as mindomo.com is because it is true CONCEPT mapping.

The difference is the ability to write on the arrows and have true links between items in different parts of the map.

Other mind map programs are really a graphical version of a bullet point list and that is why they can be exported to a neat text version. CMAP is more than that.

I "wanted" to use/like novamind but as a teacher I want more links between parts of the map and have useful text on those links.  
(Version 4.11)

NEIL_M  This program is free.

Inspiration is $69.

For free, I'm willing to overlook a lot of the missing features and shortcomings.

This pretty handy for what it is.

I'm not understanding the other reviews.  
(Version 3.10)

SQUIRRELROBERT  CmapTools 3.8 is essentially Inspiration Mind Map Software, but financed by DARPA and our friends at DOD. Have a look-see at their website:

http://www.ihmc.us/

Back to CmapTools. You can make pretty diagrams easily, but that's about it. Export to text is supported, but the actual text document is unstructured. Inspiration lets one export as Word, Mellel, AppleWorks, etc, and preserves structure. Collaboration via internet is also supported, but this is not rocket science to implement.

What you get for free (your tax dollars at work) here is a nice diagramming package and a lot of window decorations. It is like using Power Point to do engineering, a charge leveled at NASA by the Columbia investigation Board.

Summary: CmapTools looks like a poorly copied version of Inspiration 7.6. Essentially, where are the justifications for the lofty claims made by the developers on their web site?  
(Version 3.8)

ANONYMOUS  An excellent program belonging to the "Mind Map" family of software -- conceptually similar to Visio and Inspiration.

Pros: Easy to use. Versatile. Free. Cross-platform compatability.

Cons: Nothing substantial -- JVM performance penalty on program startup and when saving CMAPs. Few built-in node shapes (Can be imported from other sources).

On Balance: A strong tool to visually represent information. It is especially useful for representing the intra and inter-relationships between concepts.
