What those firms have done is provide interfaces, apps, and matching and dispute resolution services that differentiate it from Craigslist and help it build a customer base. For example, Airbnb has built its business on attractive photos of the rentals available on the site, and on its dispute resolution and customer service. That's the challenging part of building a successful startup.
But for potential entrepreneurs unsure of what kind of service they want to build, Craigslist seems like a great place to start looking.
