Yesterday I was in Paris, giving a talk to GUTenberg about LaTeX3 as part of their user meeting. The event was very well attended, and ‘official’ video recording will be available of all of the presentations. People seem very keen to hear talk I was giving, so I recorded the audio and have put it together with the slides as a video (thanks to UK-TUG for use of their Vimeo account!). I do hope it all makes sense!
