I particularly liked this challenge: "Think of five startups that you really admire and that you think were big hits. Now, do some quick research and figure out how much time/energy they spent on a big-bang launch to "release" their product to the world."

This one reminds me a bit of Joel Spolsky's "Ben and Jerry's vs. Amazon" from back in the day: http://www.joelonsoftware.com/articles/fog0000000056.html

"Both models work, but you've got to pick one and stick to it, or you'll find things mysteriously going wrong and you won't quite know why."

I think Lamarckian evolution would be a better model here.
