I think this is aimed at an audience outside the academic system, and I like the focus on active involvement with data. I think there could be an activist underpinning here - Paulo Freire style data literacy. (http://www.infed.org/thinkers/et-freir.htm)

Having said that, my Maths teacher self wants to do some work on the glossary. In the spirit of 'code talks' I'll post some definitions up and link them to the issue tracker and see what happens...
