It used to be called Touch-graph ….the one that visualised any URL. Shame it’s been dropped off the functioning web 2.0 world.

I can think of some social-education tools that do aspects of kind-of learning mapping, although not visually (that I’m aware of). For eg, elgg.net allows people to tag their learning interests – but not in a way that others with similar educational interests, and I you can’t annotate your learning topics with progressive updates.

I was just trying to keep track of all the different things my 3 yr old is learning, and then thought it’d be great to be able to visualise the different aspects and relationships of learning within an adult course that I facilitate etc.

Guessing the email validation didn’t like the ‘ ‘ in your email address – I’ll update it to accept email addresses including ‘ ‘ as soon as I get a chance (and maybe turn it off in the meantime). Cheers

Alas, I don’t know of any.

I do know one tool that implements part of the “interactive mind map” idea — the “Freemind” does “folding”.
It is one step closer to your vision than a static drawing.

The Freemind “documentation” page lists a bunch of “Alternatives to using FreeMind”.

Do you know anything that even partially implements these other ideas?

p.s.: I get a “Error: please enter a valid email address.”
You might want to look at the “best practices” for email validation

Please don’t make me add you to the
“wall of shame” of sites that reject perfectly valid email addresses.
