This is so ingenious -- I'm quite sad I didn't know about it before. Wiki Mind Map I found it in a roundabout way.  Several days ago someone reminded me about YubNub, a so-called command line for the web.  I went to look at the "Golden Eggs (particularly useful commands), and one of them was "wimi" -- creating mind maps based on the link structure in Wikipedia. I thought that was a pretty cool idea, so I took it for a spin. I looked up "meme", as I recently introduced the concept to someone. this is what I got. This is fantastic for what I call "search brainstorming", as I mentioned in my Google Notebook post. I've got a lot more YubNub commands to look into. I'm about to write another post on "search brainstorming". Hmm.
