Third day of the IxDA conference in Boulder. From minute #1, I’ve been smiling at attendees and getting about a 15% return rate of people smiling back. 

As I wander around the UMC, buying snacks and looking around, 80% of co-eds, including the harried, hectic cashiers, smile back and radiate friendliness. 

Maybe this needs to be a talk topic next year. Or a documentary. Using a hidden camera and wearing it for three days.
