One of the strengths of Posterous is that it offers a good solution to both approaches. If you like the ease-of-publishing via email, it can do it. Web? Got that too. How about via an iPhone or Android? Check. In Clayton Christensen's book The Innovator's Dilemma, he discusses two types of disruptive innovations: 1) Low-end disruptions These serve less demanding customers with low-priced, relatively straightforward offerings using low-cost business models. Look for markets with over-served customers and offer a simpler product or service. 2) New-market disruptions These serve new customers by making it easier for them to do something that previously required being or hiring specialists. Look for unfulfilled needs and create new products or services for them. Posterous is a great example of a low-end disruption. They're offering a product so damn simple that few realized it would have such an impact (like Dustin Curtis). And now they've got features that early adopters and perhaps some early majority want as well (the rich-text editor). Pretty shrewd of them.
