Here is a link to the presentation I used September 20th at the #GWC2012 in Valencia (translated in English!). The Congress was great and we all learned new points of view, I would only have liked to hear a little more on «intrinsic rewards» and a little less on «rewards» and «recognition» – (extrinsic rewards).
Thank you all for your support. Soon the organization will put the videos up in Youtube.
Yours, Lost 😉
