[FoRK] Mindmaps

I like both Wikis and MindMaps.  I find the latter to be more for 
presentation preparation than knowledge management, although the 
permanence of a master hierarchy can help there also.  Wikis need 
MindMaps (or something better that subsumes the mindmap features).

I want the best of both plus real semantic knowledge representation in 
an easy way (i.e. Wiki easy), plus generalized knowledge processing.  I 
know what part of the solution looks like, but the rest is still elusive.
