So, let's say someone creates a service that creates an online store application only for shoes (let's call this shoestring) compared to an online store application (lets call this Viaweb).
Although, the 5% who sign up do matter in determining Shoestring, it still matters that this application have something that bests Viaweb, whether it is a better interface for shoes, or whatever the one key ingredient is in differentiation. All I'm saying is that this app should have that key ingredient. It may be better as a FB app that can be sent to your friend ("hey, you wuz in my dreamz thinking of foodz").
