James wrote a bit about his experience at FrESH. An excerpt.
Attending a real-time session on the web, and being able to discuss things I am thinking about, has made all the difference in my learning. I feel like I can stay focused on a particular topic. I can ask questions to follow up on the things I am confused about. Because all participants are invited to bring ideas for what to discuss, I learn much more about the breadth of the web platform.
