[kwlug-disc] Mind mapping sw - reivsited

[unsolicited]

For some reason did some poking about wrt mind mapping software. 
Probably due to kwlug disc thread not long ago / Raul.

Seems there's 3 popular apps out there:
- freemind - hadn't hear of this until Raul.
- freeplane - recent fork of freemind.
- xmind

Any particular pros/cons of any of the above / list users of them 
caring to comment?
