Not quite as visceral as "Take this lollipop", mostly because it's a description. But I imagine if done live it could make an impact. Probably more effective in larger cities where more people are using the combination of facebook and Foursquare.
Google doc trying to answer "what will pedagogy look like in ten years' time"? Mostly higher education focused which may influence rejigging of EDC3100 - or may not.
Potentially interesting longer term implications for other education sectors.
