Pincus says if you have to ask whether something is lightning in a bottle, it isn't. His hard rule: when 60% of people who try a product come back every day, as with Facebook and Friendster, invest.

“I just think there are patterns that you can just see. There are metrics like every time you see 60% DAU to MAU, just invest. That was Facebook.
