Interesting article, but seems to really over-simplify things. There are many reasons to diversify your product portfolio. I agree that most of them don't apply to an early start-up, but the fact that it takes a quasi-infinite amount of time to perfect even just one product should not be a reason to ignore all other products. Diversification can become a valid strategy for companies once they reach a certain size.
