The thing that strikes me the most is how much fun this Expo is. Everyone seems thrilled. The vendors are excited and passionate about their products or services, and seemingly love every minute they spend talking about them. And the attendees seem enraptured as they listen and ask questions, every bit the equal in passion. It's a quintessential marketplace, bringing together people who share common interests. Yesterday in the short time I was at our booth, I had two different developers come up to me, eager to show me their app.
