People make conferences worthwhile. Lots of value comes from the technical content, the parties, the swag. But years after the event, you remember the wonderful conversations and adventures with people.
At Apple's World Wide Developers Conference, there are more than 5000 people. Sadly, I wasn't able to meet them all. Instead, I took some photos of the more interesting characters around Moscone center during WWDC 2011. Some of them are developers, but some of them are marketers, and even a few are Apple protesters who were working hard to keep things interesting.
See all of the Faces of WWDC Photos.
