In addition to being able to list your goods or services, the app has a built-in messaging and payment system, as well as a reputation, rating and feedback system. Unlike Craigslist where everything is sold pretty much anonymously, the better your services/goods are, the better your reputation can be, which leads to increased transactions in the future.
Sounds like a promising service/app – provided it gets out there and users actually decide to adopt it. Not to mention, the built in communication system should make contacting clients more efficient – since it is a smartphone app, people will probably be able to reply instantaneously.
