There’s a new on-line concept mapping tool – Glinkr.  It’s a little cumbersome to use at present, but these are early days and there’s no reason to think it won’t improve.  But I have a 24″ screen because I do a lot of mind mapping, modelling and diagramming, and this product confined me to one small rectangle when editing the map.  I hope they’ll open up the workspace soon.

With luck, you should be able to see a map I made of the many on-line mind-mapping, concept mapping and related diagramming sites here: http://www.glinkr.net/map/spot/177/

The links are hard to get at, but are in there.

This will go into mind-mapping.org in a day or so.

In case it doesn’t show if you visit their site, this is what I made:
