Sitting up front is a big deal. When the doors finally open, some folks want those seats badly enough that they will sprint the entire length of the auditorium. Since some of them don’t get much exercise, let alone running while lugging a laptop, the resulting race isn’t exactly the human drama of athletic competition. For me, this is when WWDC really begins, and I like to call it The Running Of The Geeks.
