I was one of two keynotes at Europeana Tech in Vienna in October 2011. I've posted my talk notes at My Europeana Tech keynote: Open for engagement: GLAM audiences and digital participation. There's a video of my keynote 'Open for engagment: GLAM audiences and digital participation' on YouTube (but I haven't watched it so have no idea if it works as a video).
Some of my other notes from the conference are at Notes from EuropeanaTech 2011.
