Laura and I did a version of our Echo Chamber presentation at an event in Newcastle a couple of weeks back. We had a shorter time than usual to do it in, so we took the opportunity to make a slide-deck rather than using the Prezi; it isn't as long, and as far as I'm concerned the more potential this presentation has for dissemination, the better. If we make it available in more ways, that's good - particularly in as embedable a medium as a Slideshare presentation; feel free to take this and put it wherever you like (it's on an Attribution-NonCommercial-NoDerivs licence). Laura has also uploaded this to her Slideshare account, and it's featured on Slideshare's Homepage! Woot.
We had a great time in Newcastle - thanks to Biddy Casseldon and her team for putting us on! Unlike at the other events we've presented at, the vast majority of the audience weren't familiar with who we were or what we were going to talk about, via Twitter or blogs, beforehand. We were escaping from our own echo chamber to a certain extent, and starting with a clean slate, having to win over a fresh audience as to the importance of what we were talking about. It was really gratifying to see people nodding emphatically - you really got the sense that people were having exactly the same "oh we really DO do that stuff, and it really DOES matter, and we really CAN try and fix it!" type revelations we had when we first started discussing the echolib thing 12 months ago. We were preaching to the unconverted, and I think we converted a lot of them. :)
