Clojure Mindmap by Siva Jagadeesan.
Impressive graphic but I suspect the task of building it was more instructive than the result.
Something about slowing down enough to write information down and to plot its relationship(s) to other information that makes it “sticky.”
Or it is not so much a question of speed as it is of the effort required to write it down and plot?
Do you remember information you have to look up and then type in a text longer/better than grabbing a quote for a quick cut-n-paste?
I first saw this at DZone.
