I'm fresh off the podium at ER&L - a tricksy session with my co-presenter Jill Emery on Skype and unable to hear us, though happily we could hear her. It made for a fun Q&A, with me attempting to transcribe questions in Skype's chat box as they were posed - credit to Jill for managing to understand and respond despite the typos! I'm now scanning the Twitter stream and thought I'd share a selection of the tweets as a summary of our talk. (The slides from our talk are on Slideshare). Many thanks to all our tweeters, and indeed to all the audience for their patience with the technology challenges!
