Jennifer Bove writes for Fast Company about how she and Bill DeRouchey designed the conference experience in "Interaction10: How to Design an Experience for Experience Designers." It' a great behind the scenes look at how they observed the event the year prior, and thought about every aspect of the attendee experience and designed the IXD10 event to create a service that caters to what's important to the conference-goer at every point. I'm sad I missed it. Sounds different from most conferences I've been to, for sure.
