I starting a Knowlege Manament project and would like to have as
reference the best "Wiki" system implemented using Ruby.

This project is intended to use a non linear Wiki system like
TiddlyWiki (see http://www.tiddlywiki.com) and also a full cosmology
implementation of the Personal Brain functionality (see
http://www.thebrain.com).

I have looked around about some, but it semeed to me not be able to
know its current status e.g. instiki. So can anybody help me on that?
