In Barcelona last week, Nicolas Sorel filmed me answering a few questions from Julien Chable about Open XML. It's on Wygwam's "The Tech-Ed - as if you were there!" page. Just click the link under my name in the list.
For you French speakers, Julien also posted on his blog about the conference, including a photo of the popular Open XML t-shirt.
Thanks to everyone who dropped by the booth. It was great to hear your thoughts and see so much interest in the new formats. And for those whose email addresses I didn't get (Mick? Philip?), please send an email to dmahugh AT microsoft DOT com so we can keep in touch!
