Unusually for the heppell.tv site, this link is pointing to a whole keynote talk at the wonderful uLearn10 conference, just post-earthquake, in NZ's Christchurch - run by CORE and I suppose looking back I had a hand in setting up both CORE and ULearn a decade ago.
Anyway, here's the link
For once, I have listened to this right through (it's a bit odd listening to yourself) because the feedback on Twitter etc during the keynote and after had been rather good, and watching it I'm quite pleased with how it came out - you never really know at the start because the audiences reaction tends to steer and shape to route the talk takes. It's what happens when you don't use slides.
Anyway, if you have an hour to spend (!) - have a listen.
