One comment I made during my presentation at the Eureka! business plan contest this past December was that “You don’t have to create a Yahoo! to be a successful entrepreneur. There are other paths to follow.”
A few months later, I’m starting to see this idea in different forms, all making the same point: You don’t have to work with world domination in mind. Several recent articles I’ve read have addressed this issue: The first article is from Clay Shirky about situated software and the second discusses Boing Boing. Give them a read and draw your own conclusions.
