@shnayder @WatsonEmily @dsjen @srpearce @stroilova here's the initial draft for the gender demographic data. I don't have access to real data yet, so can't quite finish up the screen-shot-and-its-interpretation piece. (Suggestions on a good illustration welcome)
May I ask: @lamagnifica  , why is the last sentence about edX Insights in parentheses here -- because it is hypothetical? It seems like an important point.
