I am truly amazed. Alongside my main project which is nowhere near release, I created a map about all things mapping with emphasis on free stuff. It can be found at http://www.metamathmap.co.uk/
I should also mention http://www.streamline.net/ who about 2hrs knew nothing about me and I managed to create the whole site really quite easily, which for me as a newbie is quite an achievement. Well done Freemind. I'll be glad to recieve feedback through this topic.
I am not going down the Wikki route just yet
