Good Wiki Software?

I’ve been thinking about the relationship between wiki’s and mind maps. It would be neat if we could go from wiki to mind map to try to see a birds eye view of our thoughts and how they progress and grow. So I’m looking for good software to try to write a project oriented mind map of ideas, materials, webpages and people… So far I found Tiddly Wiki. Does anyone have any experience with this? Should I use something else?
