We ran a summer camp program for college students for several years. It started with 40 college students and each year we started adding more people. What was interesting was that each year believed that it's group size was perfect, and that any bigger would just be too big. They said that at 40, 70, 120, 300 and beyond. I've never been able to fully understand why that is. But the fact that you get that at hackathons, summer camps and incubators alike, is really cool
