1) StartUp people, especially founders, have a heightened appreciation of Time. Big organizations build in redundancy and shared responsibility. If something doesn't get done, it's not your fault and it's not the end of the world. The business goes on. In a startup, the buck stops with you, and if you don't get it done, it doesn't' happen. Time can not be wasted

2) Startup people generally love what they do. They aren't looking for a day off. Contrast that with most people. A day off is welcome.

3) The tech industry has an "us vs the world' mentality that separates it form othe rindustries. Even my friends who wanted to work--because they had deadlines, etc--were left with no recourse. Our industry wants everyone to succeed. It's empathetic. Most people understand the pain and joy of building something, so they do everything they can to help others succeed as well. That doesn't exist (in my experience) in other industries, and it creates a community that other industries don't have. I think that's part of what we saw last week.
